Wilansky: Stan was a popular pick to exit early by our experts after a rough few weeks. But he seems to have found his inner Aussie Open form again. Stan in four.
Bialik: If ever there was a matchup that could break Isner's 70-68 fifth-set win over Nicolas Mahut in 2010, this is it: It pits two of the top 50's best servers and two of its worst returners. The edge goes to Lopez, who's more comfortable on grass and coming forward. I'll pick five sets, though schedulers hope not, because if the match goes the distance, someone will have to break serve to win it.
Garber: I know Lopez has been playing well on grass, but I'm feeling like he's about to hit the wall. Give Tall John the match in five sets, with two tiebreakers.
Isaacson: This seems a sure bet to go forever, though that's a relative term with Isner in the conversation. In a staring contest, the American at least has experience. Isner in five.
Wilansky: The question is the over/under on aces. Isner and Mahut combined for 216 in 2010. Chances are they won't get there, but I am saying Lopez in five sets. Four tiebreakers and 14-12 in the fifth. And 87 total aces.
Bialik: Bolelli played admirably to take a two-sets-to-one lead in this match -- which was suspended at 3-all in the fifth set -- but Nishikori is too good to lose here. He'll be motivated to finish quickly ahead of a showdown with Milos Raonic.
Garber: I have to go with the chalk here. Nishikori is a better player by far, and after a full day to dwell on his situation, he'll come out and win this thing.
Isaacson: Nishikori had no business extending this one. Look for him to close it out.
Wilansky: When healthy, Nishikori could be a top-five player. The break will do him some good. Nishikori will prevail.
Bialik: Mayer, who is 27, has won three matches here after winning six prior tour-level matches on grass. Dimitrov won five matches just two weeks ago en route to the Queen's title. He'll cruise in three.
Garber: This might be the most one-sided matchup in the round of 16. After struggling to beat Alexandr Dolgopolov, Dimitrov hits the dimmer here and takes Anderson out in four.
Isaacson: Mayer has never been past the second round of Wimbledon before this year, while Dimitrov seems destined for future greatness here. Dimitrov's serve will be tough for Mayer to take. Dimitrov in straights.
Wilansky: The Bulgarian put his party hat on hiatus and is making tennis his first priority. Looks like he might fulfill those lofty expectations after all. Dimitrov in four.
Bialik: Chardy's done well to get this far against a soft draw. He's never beaten a top-30 player on grass, which doesn't give him time to set up for his big shots. Cilic just straight-setted Tomas Berdych and is dangerous on grass. He'll win in three.
Garber: Cilic is having a terrific season. He'll go through and face Djokovic in an intriguing quarterfinal. Cilic in three.
Isaacson: It's Chardy's first fourth round here, while Cilic reached the fourth in '08 and '12 and will be attempting to reach his first quarterfinal. Cilic is 33-12 this year and should have little trouble. Cilic in four.
Wilansky: They haven't played in five years, when Chardy took down the Croat in Munich, Germany. But that was on clay; this isn't. Cilic in straights.
