JUNIOR MIDDLEWEIGHT DIVISION (UP TO 154 POUNDS)

2. Jermall Charlo (23-0)
Houston's Charlo -- contender Jermell Charlo's twin brother -- claimed a world title in September when he blew away Cornelius "K9" Bundrage, scoring four clean knockdowns en route to a one-sided third-round knockout victory seven years to the day he made his pro debut. In November, he made his first defense and blew out highly questionable challenger "Silky" Wilky Campfort, dropping him three times in a third-round knockout. Defense No. 2 will come against a worthy challenger in former titlist Austin Trout (30-2), whom he will meet in a Showtime main event.
Next: May 21 vs. Trout

3. Jermell Charlo (27-0)
Houston's Charlo, twin brother of titleholder Jermall Charlo, was supposed to challenge Demetrius Andrade (21-0) for a world title in December 2014, but Andrade pulled out in a beef over his purse. In March 2015, Charlo picked up his biggest win, a tight decision over Vanes Martirosyan and, most recently, he crushed former titleholder Joachim Alcine in a one-sided sixth-round knockout in October, Charlo's first fight since splitting with trainer Ronnie Shields in favor of Derrick James. Next up, Charlo will face John Jackson (20-2) for a vacant belt on the same Showtime card on which his brother will defend his title.
Next: May 21 vs. Jackson

4. Demetrius Andrade (22-0)
Andrade won a vacant world title by decision against Vanes Martirosyan in 2013 and defended it by impressive seventh-round knockout of mandatory challenger Brian Rose in June 2014. But a series of awful business decisions kept Andrade out for 16 months and led to him being stripped of the title for inactivity. He finally returned on Oct. 17, blowing out Argentina's Dario Fabian Pucheta in the second round. He was supposed to face Charles Hatley in a title eliminator, but they could not make a deal. Instead, Andrade will face more deserving Willie Nelson (25-2-1) in the eliminator on Showtime on the Ruslan Provodnikov-John Molina Jr. undercard.
Next: June 11 vs. Nelson

5. Vanes Martirosyan (36-2-1)
In Martirosyan's first world title shot, he lost a decision to Demetrius Andrade for a vacant belt in 2013. Now he is set to get his second opportunity against Erislandy Lara (22-2-2) in a Showtime-televised rematch of a 2012 title eliminator that ended in a disappointing ninth-round technical draw.
Next: May 21 vs. Lara

6. Austin Trout (30-2)
After back-to-back decision losses to Canelo Alvarez and Erislandy Lara, former titleholder Trout won four fights wins in a row (three by knockout), all against decent opposition. Trout will get another shot at a world title when he faces Jermall Charlo (23-0) on Showtime.
Next: May 21 vs. Charlo

7. Julian Williams (22-0-1)
Philadelphia's "J Rock" is always in tremendous condition and is a fan-friendly fighter who has looked sharp in recent fights, including on March 5 when he dominated unknown Italian Marcello Matano en route to a seventh-round knockout in a title elimination bout that made Williams the mandatory challenger for Jermall Charlo (23-0).
Next: TBA

8. Carlos Molina (25-6-2)
Molina, unable to fight in the United States after being deported to Mexico, got dropped twice and lost his world title via clear unanimous decision to mandatory challenger Cornelius "K9" Bundrage in October 2014. Molina has won three low-level fights in a row since, including an eighth-round decision against Reyes Sanchez on April 2 in a bout contested at welterweight.
Next: TBA

9. Liam Smith (22-0-1)
England's Smith became the first of the brothers from his fighting family to win a world title in October when he scored a huge seventh-round knockout of 2015 Boxcino tournament champion John Thompson to win the belt stripped from Demetrius Andrade. Smith made his first defense on Dec. 19 and brutalized inexperienced Jimmy Kelly en route to a bloody seventh-round knockout. Defense No. 2 will come in his hometown of Liverpool against Montenegro's Pedrag Radosevic (30-1), whose lone defeat came against former four-time middleweight titlist Felix Sturm in 2013.
Next: June 4 vs. Radosevic

10. Willie Nelson (25-2-1)
In October 2014, Cleveland's Nelson lost a competitive decision to Vanes Martirosyan and then had elbow surgery. He returned on July 11 and scored a ninth-round upset knockout of hot prospect Tony Harrison on a PBC on ESPN card. After an eight-month layoff, Nelson returned on March 25 and knocked out Jonathan Batista in the second round, setting himself up for a title eliminator against former titlist Demetrius Andrade (22-0) on Showtime.
Next: June 11 vs. Andrade
