No. 4 Roger Federer vs. No. 5 Stan Wawrinka (Third match, Centre Court): These two are meeting for just the second time since Wawrinka's Australian Open win. Wawrinka won their first match in come-from-behind fashion, beating Federer in the Monte Carlo final 4-6, 7-6 (5), 6-2, which snapped an 11-match losing streak to his friend. But this is grass and this is Wimbledon. Federer hasn't been tested through four rounds, and he hasn't been broken on his serve either. Wawrinka will need a big serving day to get his teeth into this match.
No 3 Andy Murray vs. No. 11 Grigor Dimitrov (Second match, Centre Court): Murray leads the head-to-head 3-1 but Dimitrov got the better of him in their last match, with the Bulgarian winning 4-6, 7-6 (5), 7-6 (3) in Acapulco this year. Murray hasn't lost a set in his first four matches and he's looked incredibly sharp. Dimitrov had to fight through a five-set match against Alexandr Dolgopolov, but has otherwise looked confident and composed. Dimitrov is playing in his first Wimbledon quarterfinal though, and Murray's experience should win out in the end. As much as we talk about "The New Dimitrov" this year, this has been a very different Andy Murray at Wimbledon. He's playing freely and he's been calm and composed throughout what is normally for him the most pressure-packed two weeks of his season.
No. 1 Novak Djokovic vs. No. 26 Marin Cilic (Second match, No. 1 Court): Djokovic put to rest any concerns about his left shoulder injury in a straight-set win over Jo-Wilfried Tsonga in the fourth round. He comes into this match having never lost to Cilic in nine matches, though the Croat has been able to steal a set off him in the two matches they've played this year. Not that Djokovic needs any more motivation to win the title, but if he does he'll take the No. 1 ranking back from Rafael Nadal.
No. 8 Milos Raonic vs. No. 144 Nick Kyrgios (Third match, No. 1 Court): Can Kyrgios rebound physically and mentally from his huge upset of Nadal? He'll have about 24 hours to get it out of his system before playing Raonic. Expect a lot of tiebreaks in this one. The two played in the first round of the French Open last month and Raonic won in straight sets. "There's going to be a lot of walking from side to side from his serve, and there's going to be a lot of winners in the match," Kyrgios said. "It's going to be hard to find rhythm. I'm just going to go out there and just go with my return of serve. Holding serve is going to be important, being able to make inroads on the other person's serves."
No. 3 Simona Halep vs. No. 19 Sabine Lisicki (First match, Centre Court): Halep hasn't had the stiffest competition to make her quarterfinal -- the highest-ranked player she's faced was No. 71 Belinda Bencic -- but that means she'll be fresh and ready for Lisicki, who may be dealing with a shoulder injury. The German hit 20 double-faults in her win over Yaroslava Shvedova and struggled at times to keep her speed up. Shvedova let her off the hook but Halep won't be as generous. Halep leads their head-to-head 2-1 and won their last two matches in three sets.
No. 9 Angelique Kerber vs. No. 13 Eugenie Bouchard (First match, No. 1 Court): Bouchard had her feet kicked up on the couch on Tuesday while Kerber had to fend off Maria Sharapova in three sets. The Canadian was the only woman in the top half of the draw to advance to the quarterfinals on Monday and that day off should help her get the better of Kerber, who is coming off a very physical win. The two played at the French Open and the teenager routed the German, winning 6-1, 6-2 in the blink of an eye. This is a far better surface for Bouchard's game, so I'd expect the same result.
