Top 50 fantasy prospects for 2016

— -- The year of the rookie in Major League Baseball has passed. Kris Bryant, Noah Syndergaard, Carlos Correa and many others left the prospect ranks behind in 2015. But the 2016 class of prospects has a chance to make plenty of noise and impact just as many playoff races -- both in MLB and in fantasy leagues.

To kick off our 2016 coverage, we bring you the top 50 prospects for the upcoming season. Please note these are not your traditional prospect rankings. Keith Law has you covered for that. Instead, this list considers which players have the most value to contribute to fantasy teams right now.

In addition to talent, things like playing time, ability to fill up standard scoring categories and position are heavily considered. There are a number of things that can and will happen during the next few weeks that will skew playing time -- and where a prospect starts the season -- so check back for updated rankings once the season nears.

1. Corey Seager, SS, Los Angeles Dodgers

Analysis: Seager's nickname should be "The Consensus." He is the top prospect on nearly every list. For many of the same reasons, he takes pole position here. The younger brother of Kyle Seager made his long-awaited debut in September of last season, and he wasted no time displacing Jimmy Rollins from the Dodgers' lineup. He hit .337/.425/.561 with 13 extra-base hits in 113 big league plate appearances. He tallied 58 extra-base hits across two minor league levels prior to his call-up. He can hit for average and power with a maturity that is beyond his 21 years of age. The one category he lags in is steals. That said, he will have a shot at double digits there, as well.

For at least the 2016 season, he will do all of this as a shortstop, only increasing his value. Even if he does move off the 6 spot, the potential to hit .300 with upward of 30 home runs in the middle of a talented lineup will make him a candidate as a top fantasy pick for years to come.

2. Steven Matz, LHP, New York Mets

Analysis: Unlike Seager, the opinion on Matz is less uniform. Keith Law ranked him in the mid-30s on his list, citing durability concerns. He checks in at No. 2 here because he has the chance to make a bigger impact and serve a larger role than any other rookie hurler.

Law's concerns are valid. Matz has never tossed more than 150 innings in a season. However, he pitched 140 2/3 innings in 2014 and a career-high 141 frames last season, including 35 2/3 in the majors. Matz has three pitches that grade out average or better. The attack starts with a mid-90s fastball, followed by a plus changeup. The off-speed offering is good enough to fend off platoon splits, while the upper-70s breaking ball should keep fellow lefties off balance. He controls all three pitches well, which should translate into a healthy strikeout-to-walk rate. Once more, the health of his body is the largest question left to be answered.

3. Byron Buxton, OF, Minnesota Twins

Analysis: Buxton had as much helium as any other prospect heading into 2015. However, unlike the many studs from the same class, his hype balloon has deflated a bit due to a poor showing at the top level. The former second overall pick is a dynamic defensive center fielder that can run with the best of them. He was promoted, perhaps prematurely, from Double-A to the majors, where he struggled out of the gate before missing time with a thumb injury. He performed slightly better upon return, but he is not as polished as Seager due to a lack of experience at the upper levels.

Depending on what happens in Fort Myers this spring, he could break camp with the Twins or spend time at Triple-A getting those reps. He still projects to be an above-average hitter -- although his aggressive approach might weigh down his on-base percentage -- with double-digit home runs and the chance to win the stolen base title.

4. Tyler Glasnow, RHP, Pittsburgh Pirates

Analysis: You could make the argument that Glasnow is the third-best starting pitcher in Pittsburgh's organization. Meanwhile, the contending Pirates were wise to bring in veterans like Ryan Vogelsong and Jonathon Niese in lieu of resting some of their playoff hopes on an unproven youngster. If Glasnow pitches up to his height and ability, overtaking a veteran should not be a tall task.

Barreling down from his nearly 7-foot frame, he tosses a hard fastball in the mid-90s that is flanked by a curveball that is a MLB-caliber pitch. The development of his changeup, which at times is thrown a bit too hard, will factor into his ultimate ceiling. As it stands, he has two bona fide offerings with decent control and the body to take the ball 30-plus times a year. If the changeup develops or should the control improve and manifest into command, look out.

5. Kenta Maeda, RHP, Los Angeles Dodgers

Analysis: While he isn't your typical prospect -- due to his age (27) and experience (eight seasons with the Hiroshima Carp) -- Maeda is a rookie in the eyes of Major League Baseball, and thus qualifies for this list. The slender right-hander will need to rely on manipulating speeds with his changeup and a slider (he also has a curveball) and location -- which should be easy given his ability to control the zone -- to make up for the lack of overpowering stuff (low-90s fastball) and size.

Though he has proven to be durable as a professional in Japan, there is pause about his previous workload and how that will impact his future ability to start. His incentive-laden contract basically confirms those concerns as real. Nonetheless, he has the chance to rack up a lot of wins on a talented Dodgers club while potentially contributing positively in ERA and WHIP.

6. Byung-Ho Park, 1B/DH, Minnesota Twins

Analysis: Park could be three or four spots too low on this list or he could be wildly overrated and not even worthy of inclusion. That illustrates the span of uncertainty surrounding the former Korean Baseball Organization (KBO) MVP. A dynamic hitter in terms of both average and power in Korea, there is a fair amount of question about how the hit tool will translate -- specifically, his bat speed versus the American game's velocity.

On the plus side, many believe he will continue to hit for power, although not at his previous rate. He provides little to none in terms of position flexibility, and not much is expected from his legs. There is a fair chance he hits .220 with some long balls sprinkled in between the outs. Conversely, he could hit .275 and belt 30 home runs. The potential for the latter, as well as the strong opportunity for regular at-bats, lands him in the top 10 for now.

7. Jose Berrios, RHP, Minnesota Twins

Analysis: Another Twin makes it into the top 10, and it is easy to see why Keith Law has them as a top-three farm system even without Park's inclusion. If you followed our lists from last season, you will remember that I am all-in on Berrios. The lack of size, along with a lack of zip and movement on the fastball are valid points of unease. He is listed at 6-foot, 185 pounds, and the fastball can sometimes look like a 92 mph arrow to the target.

On the other hand, he made it through a full schedule of starts last season and has two above-average secondary pitches with the ability to control and command location. The development of his changeup last season should offset some of the fastball concern, as hitters will have to determine which pitch is coming midflight while adjusting for speed. Meanwhile, the curveball can generate outs now. As was the case last season, it is a matter of when the Twins will give Berrios the opportunity. He's ready.

8. J.P. Crawford, SS, Philadelphia Phillies

Analysis: Fans of the Phillies' High-A affiliate, the Clearwater Threshers, are fully aware of Crawford's ability on the diamond. A year after demolishing the Florida State League in a matter of weeks, the 20-year-old returns to the site this spring looking to make his case for inclusion on the major league roster. The rebuilding organization has little reason to rush its prized prospect to the majors, but despite his age and experience, Crawford might get the call sooner than later based on merit.

His approach at the plate is more advanced than the average player of the same age, and his hit tool follows suit. Beyond that, he owns the chance to spray extra-base hits across the yard and pop a dozen balls over the wall. He is a tremendous defender at shortstop and has an opportunity to introduce even more of his plus raw speed between the lines, like his cousin Carl. The chance to impact multiple categories as a full-time shortstop earn him this ranking, even if we have to wait a little longer.

9. Joey Gallo, 3B/OF, Texas Rangers

Analysis: Gallo's power might be the best tool of any player on this list. It is an 80-grade, game-changing pop that is as clear in batting practice as it is during games. His six major league home runs covered 2,584 feet, according to the ESPN Home Run Tracker, with the hottest one coming off the bat at 114 mph.

The problems start, however, when the home runs stop. As expected, advanced pitching tore apart his average and sank his on-base percentage, even though he walked at an above-average rate. He struck out in nearly 50(!) percent of his 123 plate appearances after striking out 40 percent of the time in Triple-A. Unlike Park, who may or may not hit for average, it is widely accepted that Gallo simply will not. That said, hitting .230 with a .330 OBP and 40 home runs will pass. Hitting .200 with a .300 OBP, however, is not going to fly for long.

Defensively, his arm is nearly as good as his power, which allows him to play at third base or in a corner outfield, lending to some positional flexibility. He turned 22 in the offseason, so there is still time for the improvements needed to make him a star.

10. Trea Turner, SS, Washington Nationals

Analysis: Opinions differ on Turner's ultimate ceiling, but nearly everyone agrees he is the best option the Nationals have at shortstop, and it seems silly that he will have to pass Danny Espinosa and the ghost of Stephen Drew in order to get the job. Meanwhile, a little competition never hurt anyone, and Turner's ability to hit and run should set him apart from the veterans ahead of him. Washington had to wait half a season after acquiring Turner from San Diego via Tampa Bay before getting a first-hand look at their future shortstop.

Regardless of level or organization, Turner continues to hit and impress on the bases, save for the inconsistent playing time he received with the major league club at the end of the year. The mechanics of his swing are not perfect, but the sum of all parts produce a plus tool. The power output is likely limited by a wiry base. Though he is not a standout defender at shortstop, he is adequate enough to play the position with tremendous foot speed as a fielder and runner. It should not take long before the "Mr. Steal Your Base" nickname catches on.

11. Jesse Winker, OF, Cincinnati Reds

Analysis: Winker might be the epitome of how this list differs from conventional prospect rankings. He is a fine prospect by all accounts, and worthy of top-50 inclusion. He is limited defensively -- likely to left field -- and is not much of a runner otherwise. Those factors limit his ceiling quite a bit.

What makes him a top-50 prospect in the real world but a top-15 fantasy prospect is his ability to put barrel to ball. Winker is a hitter above all else. He has the chance to hit near the .300 mark, with 15 or more home runs. Also factoring in to his placement here are the playing time and ballpark factors. The Reds are set to play an uninspiring platoon in left field, and the Great American Ballpark is an offense-friendly environment. Once the clocks for service time and super-two arbitration pass, Cincinnati should let the kids play, and Winker should be one of the first to get the call.

12. Hyun-Soo Kim, OF, Baltimore Orioles

Analysis: Our second KBO import, Kim comes to the states with a drastically different profile than Park. However, he brings similar uncertainties with him, as we are still learning how players transition between the two leagues. The recently turned 28-year-old is penciled in as Baltimore's primary left fielder. His reputation as a line-drive hitter with on-base chops might land him a spot at the top of the order, which increases his value with hitters like Manny Machado, Chris Davis and Adam Jones behind him.

Still, some wonder if his swing will translate against sliders and changeups diving away, and it is unlikely he will walk at the same rate he did in Korea. This takes some luster off his sparkling .438 OBP from 2015. If he can maintain just a decent amount of his previous output, he has the chance to rack up plate appearances and runs scored in what looks to be a solid lineup.

13. Josh Bell, 1B, Pittsburgh Pirates

Analysis: Once again, getting production from first base was an issue for the Pirates last season. This winter, they signed John Jaso to platoon with incumbents Michael Morse and Sean Rodriguez. Offensively, that seems like a fine plan. However, it gets dicey from there. Jaso, a former catcher, is a fine left-handed hitter but is not much of a defender, and his next start at the cold corner will be his first. He also has missed significant time because of injury during the past three years. Morse is no dynamo defensively, and Rodriguez is better served in small doses.

Enter Bell, who is a hitter. He is a big man, with a potentially big bat. The frame and strength have not translated into home runs yet, but the hit tool is a plus, as is his understanding of the zone. Unfortunately, like Jaso, he is a first base convert, and the reviews last season were unkind -- to be nice. He is a decent athlete, so time and repetition will go a long way in fixing that. If so, he could be ready by the middle of the season.

14. Hector Olivera, OF/3B, Atlanta Braves

Analysis: One of the more decorated international signings from a season ago, Olivera signed for $62 million with the Dodgers last spring. That was the last bit of good news he received all year. His arrival to the U.S. was delayed into the regular season. Once he arrived, he was rushed into game action -- in which he struggled -- and then suffered a variety of minor injuries. As if that were not enough, during the same time he was traded from Los Angeles to Atlanta. He made his MLB debut in September with modest production, but the year itself was a loss.

Many believe the 30-year-old will ultimately end as a bust due to the original contract and questions about his ability to catch up to big-league pitching, as well as durability issues. As valid as those points are, I am willing to grant somewhat of a reprieve on last season and look forward. The Braves are paying him to play -- probably left field, with some third base mixed in -- which means he should get plenty of opportunities to hit. Although a reading on the hit tool remains up in the air, his power should hold, and that could mean 20 or more home runs with the chance to drive in some runs from the middle of the order.

15. Blake Snell, LHP, Tampa Bay Rays

Analysis: In search of upgrading the roster at another position, the Rays have spent most of winter shopping one or more of their major-league starters, with the idea that Snell will join the rotation sometime in early 2016. That time probably will come after the super-two arbitration clock runs out of batteries.

Snell is a two-time pitcher of the year in the Rays organization, which drafted him in 2011. Leading with a mid-90s fastball from the left side, he compiled a 1.41 ERA across three levels in 134 cumulative innings in 2015. He tosses a big, looping curveball and continued to make strides with the changeup. His control was greatly enhanced, perhaps as a byproduct of maturing and opening up a bit more to instruction. The upside for a strikeouts -- and maybe ERA -- boost is tremendous.

16. Jose Peraza, 2B/SS, Cincinnati Reds

Analysis: Another staple of last year's weekly top 10 fantasy prospect lists, Peraza is on his third team since we began tracking his progress -- which has not advanced much during the timeframe. A former shortstop with the Braves' organization, he moved across the bag to accommodate the major-league depth chart, and even ventured into center field in hopes of finding an easier way onto the 25-man roster.

He was shipped to the Dodgers during the summer, and made his MLB debut with Los Angeles soon after. He looked primed to be Seager's double-play partner for years to come, until he was traded to Cincinnati, where he is once again behind veterans on the depth chart at several positions. Peraza's stock took a bit of a hit after a mostly stagnant season and limited profile. He should hit for average and steal a ton of bases, but the average will be mostly empty, and his dislike for walks will limit the on-base chances to steal. If/when Brandon Phillips is traded, he should be an immediate starter at the keystone and help fantasy owners in the average, steals and runs scored departments.

17. Jon Gray, RHP, Colorado Rockies

Analysis: The third overall draft pick in 2013 made his MLB debut last season, almost missing out on eligibility for this list after tossing 40 2/3 innings. Pitching from a large base, he routinely tossed his fastball in the mid-90s, backing it up with a hard, mid-80s slider and a changeup in the same neighborhood. The slider, previously his prized piece, is a hot-button issue. Depending on what day you see him pitch, it can look like the pitch that carried a previous plus rating down to an average breaking ball without much behind it. The changeup is clearly the third wheel, so the consistency of the slider's quality as well as fastball command is paramount.

Gray missed Keith Law's top 100 list altogether but was ranked No. 33 by Dan Szymborski's ZiPS projection. He will have plenty of opportunities to pitch in 2016, and could approach a strikeout-per-inning pace. Just don't count on much help in the ERA and WHIP categories.

18. Robert Stephenson, RHP, Cincinnati Reds

Analysis: The Reds project to finish near the bottom of the National League standings but will have plenty of intrigue as players like Winker, Peraza and Stephenson are promoted. The right-hander is almost certainly one of Cincinnati's top five starters as it stands today. Strikeouts should come easy, as he already has two plus pitches in his fastball and breaking ball, with a third -- a changeup -- on the cusp of being above average.

On the other hand, a lot of pitchers could crack the Reds' rotation these days, and Stephenson needs more polish. The three C's apply here: consistency, control and command. Once Stephenson can show additional competency in these areas, he should be good to go for a full workload, which could come in late spring or early summer.

19. Michael Fulmer, RHP, Detroit Tigers

Analysis: Though the Tigers landed only player on Keith Law's top 100, their lone representative is a quality one. Acquired last July from the Mets in exchange for Yoenis Cespedes, Fulmer has yet to throw a pitch at the Triple-A level but is pretty close to being major-league ready as is. He owns a plus fastball that gets in the upper-90s and lives comfortably a few ticks lower. The other plus offering is a rugged slider that should have no trouble generating outs. Similar to many other prospects, the off-speed pitch is third in the order. Meanwhile, Fulmer's changeup is solid, if not better. To put a ribbon on the package is above-average control of the arsenal.

The one drawback is durability. He has yet to throw 130 innings in a season, has dealt with arm issues in the past and does not have the smoothest delivery. Starting the season in the minors is not the worst thing, as his early-season workload can be monitored and manipulated. Once called up, he should help across the board as a middle-of-the-rotation guy.

20. A.J. Reed, 1B/DH, Houston Astros

Analysis: Reed flat-out dominated the competition last season. He mashed in Double-A to the tune of .332/.405/.571, with 11 home runs in 53 games, proving his start to the year in the High-A California League (.346/.449/.638, 23 HR, 81 RBIs in 82 games) was not simply a product of his environment. The combined production earned him ESPN Prospect of the Year honors for 2015.

Reed might not continue to hit for as high of an average at the top level, as reports on his bat speed vary. What he should do is hit a lot of home runs and post solid on-base percentages as a first baseman or designated hitter. The Astros owe Jon Singleton a few million dollars, which means they probably will give him a fair chance to earn that money first. From there, Reed may be their next best option.

21. Nomar Mazara, OF, Texas Rangers

Analysis: Mazara is a top-10 prospect overall -- and even top-five, to some evaluators. He has the prototypical corner outfield profile, and could hit between .275 and .290, and approach 30 home runs as a regular. He has filled out quite a bit since his then record-setting signing in 2011 with large, strong paws, and should tap into some of that bulk as he advances. He hit extremely well across three levels last season, including a late-season stint in Triple-A.

The reason he drops down on this list is he is probably best served spending most of the year back in Round Rock, and the Rangers have options in the outfield, including the No. 9 prospect on this list. Nevertheless, the tools are too loud to ignore in case of a surprise promotion, so keep the name at the front of your mind.

22. Jorge Lopez, RHP, Milwaukee Brewers

Analysis: After several seasons honing his craft at the lower levels of Milwaukee's system, Lopez made the leap from Double-A to the majors, tallying two starts at the end of 2015. The former second-round pick throws the heater in the range of 92-95 mph, with a low-80s hook and a tantalizing changeup to fend off left-handed hitters.

He has put on about 20-25 pounds since his time at Caguas Military Academy, and now projects to be a three-pitch starter capable of taking the ball 30 times a year. There is top-of-the-rotation upside, if he can make some minor improvements in control and command. A successful audition in the middle of the 2016 season could put him in line for a full-time gig in 2017.

23. Brett Phillips, OF, Milwaukee Brewers

Analysis: The Astros paid a premium for Carlos Gomez at the trade deadline last year, with Phillips going to Milwaukee as part of the haul. A tool-box of a player, he does a little bit of everything well, without a true carrying tool. Phillips is a tenacious defender, currently capable of playing center field, with a strong arm that will serve him well should he need to move to right.

Offensively, he has an above-average hit tool with a good approach, average or slightly better pop and the speed to move once aboard. This might be bullish, but there is the chance of a 20/20 season sometime very soon. The Brewers will attempt to get by this season with a bandage covering their opening in center field. A strong start by Phillips might entice them to rethink that plan.

24. Mark Appel, RHP, Philadelphia Phillies

Analysis: Twice selected in the first round, once as the No. 1 overall, Appel's first major-league pitch will be for a different organization than the one(s) that selected him. The Astros parted with Appel to get Ken Giles this winter. The change of scenery could serve Appel well, as the expectations have now been reset and he will attempt to develop under a new set of organizational philosophies.

As is, Appel can walk into a big-league rotation as a back-end starter with a plus fastball, firm slider and workable changeup. He is probably better served trying to re-incorporate a sinker into the mix, as his traditional fastball tends to flatline to the plate. He has OK control at the moment. As mentioned, he could be the Phillies' third- or fourth-best starter right now, but with some improvements and increased consistency developed in the minors, he can once again approach upside more fitting of his draft status.

25. Trevor Story, SS, Colorado Rockies

Analysis: Once the heir apparent to Troy Tulowitzki, Story is no longer even the best shortstop prospect in the Rockies' system. That honor now belongs to Brendan Rodgers. That said, Story might get a season or two to prove himself at the position before Rodgers is ready. Jose Reyes is currently atop the Rockies' depth chart, but his status is clouded by potential suspension. And even if available, Colorado probably would prefer him on someone else's roster. This might give Story the window of opportunity mentioned above.

Far from a star, the 23-year-old would be an above-average placeholder of the six spot. He can make the ordinary play, but is unlikely to steal Nolan Arenado's thunder on the left side. Offensively, he has solid power for the position, and can move pretty well. The approach is iffy however, and he might hit only .250 in a good year. With the backing of Coors Field, he could be a sneaky source of production without the price tag of other shortstops.

26. Tim Anderson, SS Chicago White Sox

Analysis: Here is another case where the prospect is probably the best option in the organization, but for one reason or another figures to start the season playing in the minor leagues. Anderson, who has tremendous natural ability, has made huge strides during the past year transitioning from raw athlete to baseball player. He has 70-grade speed, and has so far shown the defensive chops to stick at shortstop.

Despite an overly aggressive approach -- he walked in only four percent of his plate appearances -- he maintained a .312 average as a Southern Leaguer last year. Anderson's power profile is limited, but he could hit .275 as a bottom-of-the-order hitter -- if his on-base ability doesn't improve -- while swiping 50 or more bags.

27. Aaron Blair, RHP, Atlanta Braves

Analysis: Part of the massive haul the Braves received in exchange for Shelby Miller this winter, Blair comes to Atlanta ready to contribute to the big-league team immediately. The former hurler for Marshall's Thundering Herd tosses a heavy, low-90s fastball that generates ground balls in bunches. His right-handed changeup is a plus offering, and can be used to combat the opposite hand. His curveball is a slightly below the off-speed but shows promise.

Though he might not rack up strikeouts, his ability to throw strikes and induce ground balls should lead to a tidy ERA with a solid WHIP and a lot of innings pitched.

28. Braden Shipley, RHP, Arizona Diamondbacks

Analysis: Blair's former teammate overcame mechanical difficulties to post a 2.66 ERA in his final 14 starts of the season, and is poised to make his big-league debut at some point in 2016.

They say to always bet on the athletes, and Shipley checks all the boxes. He has a solid, mid-90s fastball followed by a 60-grade changeup and a curveball that is not far behind. Should the changes made in the second half of 2015 stick, he might be the Diamondbacks' first call in the event of an injury.

29. Gary Sanchez, C, New York Yankees

Analysis: Sanchez has been a prospect for longer than some professional ballplayer's careers. He finally broke through the Double-A ceiling after spending the majority of the past three seasons in Trenton. Despite that fact, he just turned 23 last December.

Speaking of age, Sanchez seemed to answer some maturity-related questions last season, becoming more dedicated to the craft. He might never be Yadier Molina behind the plate, but will not need to be, provided he hits up to his potential. He has booming power, and should hit for a fine average otherwise. He is currently behind the offense-challenged Austin Romine on the depth chart; however, that order might flip in the event of an injury to Brian McCann.

30. Max Kepler, OF Minnesota Twins

Analysis: The German-born Kepler has made great strides as a player since signing as a teenager in 2009. Now 23, he is on the verge of becoming a contributor at the highest level. He briefly made his debut with the Twins on the heels of a breakout campaign in Double-A. In 482 plate appearances, he hit .322/.416/.531 with 54 extra-base hits.

A freakishly good athlete, he is expected to continue to hit well at the upper levels with a lot of extra-base hits, even if he maxes out in the mid-teens in home runs. Kepler is a good defender, capable of tracking balls down in center field. But with former Chattanooga Lookouts teammate Byron Buxton in center, he probably will shift to right as another former teammate, Miguel Sano, tries his hand in left.

31. David Dahl, OF, Colorado Rockies

Analysis: Dahl was involved in one of the scariest moments of last season, when he was part of an outfield collision that resulted in a lacerated spleen. A testament to his dedication, he opted to have the spleen removed to make a quicker return to the field.

The 10th overall pick in 2012 does mostly everything well and with ease. He has plus bat speed and running ability to match. He is true center fielder capable of putting up high averages and a good number of extra-base hits. His approach is currently too aggressive for the top level, but his other skills should get a boost from the Coors Field environment.

32. Aaron Judge, OF, New York Yankees

Analysis: Big. The adjective describes both Judge's size and his ability. A very atypical prospect, the near seven-footer has rare athletic ability. Though he has the athleticism to track down balls in center field, he probably will break in as an above-average defender in right.

The frame also gives him an astounding amount of raw power, 70-grade at its apex. The pop has not quite transitioned in game action yet, but there have been flashes. Although the long limbs and levers will make it difficult to maintain high averages, he could hit .265-.275 and smash 30 home runs playing half his games in the Bronx.

33. Bradley Zimmer, OF, Cleveland Indians

Analysis: It did not take long for Brad to overtake his brother Kyle as the top prospect in the family. This past August, I suggested "if you are not familiar with Zimmer, allow yourself some time to get to know him." On the strength of a great first full season as a professional, the former San Francisco Don went from a fringe top-100 prospect all the way to 21 on Keith Law's most recent ranking.

Another gifted athlete, he plays a smooth center field with long legs that helps him cover ground in the outfield and on the bases. He started to tap into some of his power, collecting 16 home runs across two levels in 2015. As a full-timer, he has 20-home run potential, with the chance at 30 steals and a solid average.

34. Lucas Giolito, RHP, Washington Nationals

Analysis: At minimum, Giolito enters the season as the top right-handed pitching prospect, and is probably the top overall pitcher in the minors, although our next name has some claim to the title as well. The stuff invokes superlatives and expletives alike. The upper-90s fastball is double-plus, and the curveball is right around the same grade. The changeup, which is third in the order and would be the second-best pitch in most arsenals, has come on strong as the Nationals have keyed in on the development of the off-speed pitch.

Giolito wraps up the package with above-average control that should soon turn into above-average command if he is not already there. Washington will continue to be conservative about his usage, which why he is not at the top of this list. But make no mistake, this is an ace profile.

35. Julio Urias, LHP Los Angeles Dodgers

Analysis: The best left-handed pitching prospect in the game, Urias' low ranking has nothing to do with talent, and much to do with opportunity. He has three plus or better offerings in his fastball, changeup and curveball. He also can throw them for strikes, and is to the point where we can start talking command.

He drops to the bottom half of this list because he might not reach the majors this season. For a variety of reasons, he has yet to cross the century mark in terms of single-season innings, so the Dodgers will be diligent in cultivating his arm with regard to workload. At the same time, should he somehow sneak on the 25-man roster, he is immediately worthy of you consideration.

36. Jorge Alfaro, C, Philadelphia Phillies

Analysis: A key piece of the Cole Hamels trade in July, Alfaro's 2015 was a wash because of left ankle surgery. He has two tools that grade out as 70 or better, with a cannon for an arm and some of the loudest raw power you will see; especially from a potential backstop.

Potential is the key word there, as new catching coach John McClaren will have to advance his ability to call games and improve as a receiver. For his part, the 22-year-old is already soaking up what knowledge he can from the man he is trying to replace, Carlos Ruiz. Chooch's job is safe for this season, but a strong showing at the plate and growth behind it could have Alfaro in Philly before long.

37. Marco Gonzales, LHP, St. Louis Cardinals

Analysis: After cracking the major-league roster in 2014, Gonzales spent most of last season in Triple-A working through and around soreness in his throwing shoulder. He was limited to 19 total starts, including one for the Cardinals. Now, he's well-rested coming into camp and he starts sixth on the depth chart in the rotation, probably needing someone else to be injured to get a chance to start back in the bigs.

Going back to Memphis would not be a terrible fate as he eases back into a starter's workload. The lefty has two secondary pitches that grade as plus, with a changeup leading the way. His fastball is pedestrian, and he will need to command and control it well for the other items to work. Regardless of role, he should pitch for St. Louis in 2016, with the potential for being a viable fifth starter a completely realistic outcome.

38. Richie Shaffer, 3B/OF, Tampa Bay Rays

Analysis: It's tough to get a read on how the Rays feel about their former first-round pick. After a slow rise through the system, Shaffer broke out in 2015, showing the power potential he had with Clemson. He hit 30 home runs across three levels last year, with four coming at the highest.

The swing and approach will leave him susceptible to strikeouts. In fact, he might top out as a .250 hitter, but with decent walk rates and the chance at 25 home runs with regular work. The Rays should probably hand him the keys to first base and let his power shine. Instead, the team has incumbent James Loney and brought in Logan Morrison and Steve Pearce this winter. It might take a couple of spring trades to get him the opportunity for which he appears ready.

39. Jake Thompson, RHP, Philadelphia Phillies

Analysis: The Hamels trade has the chance to be an all-timer for the Phillies, with Thompson as another talented piece of that puzzle. The big Texan has a prototypical starter's frame and could be a consistent source of innings pitched and strikeouts.

He tosses a low-to-mid 90s fastball, with a good idea of where the pitch is going. His future out-pitch is a slider that already grades as plus, and can be a bit better. Likewise, his average changeup stands the chance to improve as well. He is more of a No. 3 than a No. 2, but is no less than a No. 5 as it stands today.

40. Jose De Leon, RHP, Los Angeles Dodgers

Analysis: De Leon is at the same time in the best and worst organization for himself. On one hand, the Dodgers are a great spot for him; a team that took him in the 24th round, and has helped him slowly develop into a top-100 prospect without much fanfare or need to rush. On the other hand, he is probably seventh or eighth on an extremely deep depth chart, and will need some outside help if he is to make his debut in 2016.

The Robin to Urias' Batman, he did something his lefty counterpart has yet to do: Pitch 100 innings in a season. He hides his low-90s fastball well, and has been riding a plus changeup through the system. His curveball is just about average. The development of the third pitch, along with tightening up the fastball location, will determine if he is can be a low-end No. 2/No. 3, or a solid fifth starter.

41. Brandon Drury, 2B/3B/SS, Arizona Diamondbacks

Analysis: Drury's game will generate terms like "gamer," "grinder" and other adjectives for "good player who tries hard without standout ability." He is actually the type of prospect I like more at the highest level in a Logan Forsythe type of way.

He has decent power from the right side, and could top 15 home runs if given enough plate appearances. Like the rest of the game, the hit tool is a solid average. He is versatile enough to play up the middle and at hot corner, but looks more like a fit for the keystone. The infield prospects Arizona has graduated in recent years have turned out mostly disappointing, which leaves room for Drury to take someone's playing time.

42. Hunter Renfroe, OF, San Diego Padres

Analysis: Renfroe's prospect status took a bit of a hit as his progress was a bit stagnant at the Double-A level before picking it up once he was promoted to El Paso. The scale of discipline falls heavily on the strikeout side, a fact that is not likely to change as the level of competition increases. With the average-ish hit tool, Renfroe will have to hit for power to be a regular in San Diego.

The good news is that the big boy out of Mississippi State could be the Padres' best power hitter since Adrian Gonzalez. Despite his size, he moves well in the field, and along the bases. He will get a chance to impress decision-makers in camp, and perhaps give even extra incentive to move some of the team's overpaid veterans (if they can find a buyer, of course).

43. Lewis Brinson, OF, Texas Rangers

Analysis: Brinson is the type of prospect that scouts dream about. Long and athletic, he has plus speed and power, and plays above-average defense in the middle of the outfield. A true center fielder, the 29th overall pick in 2012 hit well across three levels in 2015, which ended with Triple-A Round Rock. He showed an improved approach, despite playing most of the year as a 21-year-old.

There is legit 30-30 potential, provided he can continue to improve in 2016, with the chance to become an MLB regular in 2017.

44. Yoan Moncada, 2B, Boston Red Sox

Analysis: Moncada spent most of 2015 adjusting to life and the game in the United States; quite the task for someone who will not turn 21 until right around Memorial Day. The hype train has lost a bit of steam, but we're talking going from superstar to All-Star, which is still plenty of talent. In an age when we have a lot of switch-hitters in name only, Moncada is a legit force with the stick from both sides.

I believe he will approach the 20-homer mark as he matures both physically and in terms of his understanding of advanced pitching and the American strike zone. As mentioned above, he is of an All-Star caliber; however, the Sox will make sure to bring him along at the correct pace, which limits his value for fantasy owners in 2016.

45. Manuel Margot, OF, San Diego Padres

Analysis: Acquired in the Craig Kimbrel trade, Margot instantly became the Padres' prized minor-league prospect. A true center fielder defensively, he projects to settle near the top of the lineup as a source of extra-base hits and steals. He couples an above-average hit tool with an advanced feel for the zone that should result in a good on-base percentage. He is also a plus runner that could challenge for a stolen-base title.

His thin frame probably will limit his power to the gaps -- especially in Petco -- but it would not be a shock if he hit 10 or so home runs at some point. Even without the long ball, he should top 50 extra-base hits otherwise. Like Renfroe, he will have to wait until the Padres clear some space, but could be the central player in a revamped outfield soon.

46. Jorge Polanco, SS, Minnesota Twins

Analysis: There are certainly more talented players left off this list, but Polanco has some useful skills, and perhaps more important, a bigger window of opportunity than others who were omitted.

He is a high-contact switch-hitter who is capable of producing solid averages from both sides. The left-handed stroke is more conducive to power, but the output is limited to about a dozen homers in total. He is a decent runner that could rack up double-digit steals. The path of least resistance currently runs through shortstop, a position at which he is playable. A solid average, 10-12 home runs and little more in steals makes him a player to remember in case of a need during the season.

47. Willson Contreras, C, Chicago Cubs

Analysis: Just what the Cubs need: another talented position player on the verge of making an impact at the highest level. How is this for a season? Contreras, who was unranked on Law's top 100 last year, vaulted up to 27th this year on the heels of a breakout campaign. Playing for Double-A Tennessee, he hit for a cool .333 in 521 plate appearances.

The contact skills are real, and he has a keen understanding of balls and strikes. Those attributes should lead to healthy averages and on-base percentages. His career high in home runs is 11, set back in 2013, and that seems like a decent cap as he is currently packaged. Aside from the offense, he has a highly regarded arm, and nuance for the finer parts of catching. A first half that resembles anything like last year could land him in Chicago for the summer.

48. Jeff Hoffman, RHP, Colorado Rockies

Analysis: The East Carolina product was in the mix as the top pick in 2014, but instead spent the year recovering from Tommy John surgery. He returned to the mound in early 2015, and was promptly traded from Toronto to Colorado in the Troy Tulowitzki deal.

Hoffman boasts a pair of plus pitches, with a mid-90s fastball and a knee-buckling hook. His changeup needs work as it can resemble a half-hearted fastball. He needs some polish in terms of location, but as noted several times before, it is wise to bet on the athletes, and Hoffman fits the mold. Despite the missed time and lack of experience as a professional, he could be in the majors by the end of this year.

49. Orlando Arcia, SS, Milwaukee Brewers

Analysis: Arcia, a top-10 prospect overall, will be the Brewers' regular shortstop. The question is when. The club already cleared a spot for him by trading Jean Segura earlier this month. Time and Jonathan Villar are all that stands between him and the six spot.

Arcia is a dynamic defender, and will regularly compete for year-end accolades. He projects as both an above-average hitter as well as a runner. Power is not a big part of his game, although he will run into a few homers, and will litter the gaps with doubles and triples. He does not walk much but does not strike out much either. Though he should not be rushed, there is a chance he reaches the majors before he turns 22 in August.

50. Nick Williams, OF, Philadephia Phillies

Analysis: Another Ranger-turned-Phillie by way of the Cole Hamels swap, Williams is a toolsy outfielder than has apparently made the athlete-to-ballplayer transition during the past 12 months.

He projects as a center fielder when he breaks through, with the aptitude to hit both for power and average as a hitter. From there, Williams should add 10 or more steals as an average runner. Currently, the discipline is skewed too much toward avoiding strikeouts, so his on-base chances will be limited. The Phillies have options in the outfield, yet few with this type of upside.
