No. 3 Roger Federer will take on No. 9 Marin Cilic in the Wimbledon quarterfinals on Wednesday. Federer leads their head to head 5-1 but Cilic completely overpowered Federer in their last meeting at the 2014 U.S. Open semifinals. At 6' 6", Marin Cilic has more firepower than Federer. If he can control that power, Cilic is extremely difficult to beat. So far through four rounds here Cilic has played very solid, consistent tennis—177 total winners and just 74 unforced errors. As good as his serve is, it's his ground game that is truly the barometer of his game. Cilic’s 60 forehand winners to just 33 forehand unforced errors tell just how solid he is playing.

Federer has served almost as well this year as he did last year and that will be key against Cilic, but he will need to step up his game from the baseline if Cilic maintains his current level of play. In their U.S. Open match Federer was broken four times and managed just two break points against Cilic's serve. Federer will need to mix up his game, change pace and spin, and go big when it's not expected. Roger has the best grass court record in the Open Era and will need to harness all his experience to get past the power of Cilic.

Federer’s Wimbledon highlights:
• Very strong serving: 38 aces, 2 double faults, 82% 1st serves won, 65% 2nd serves won, broken just twice in the tournament, faced only eight break points in 58 service games
• Solid return of 1st serve (39% won), below average returning 2nd serves (50% won ), converted 37% of his break chances
• Strong forehand performance (49 forehand winners, 32 forehand unforced errors)

Cilic’s Wimbledon highlights:
• Big 1st serve: 76 aces, 134mph top speed, 90% 1st serves won, dropped serve 3 times and faced 11 break points
• Big ground game 60 forehand winners, 29 backhand winners
• Playing solid tennis: 177 total winners and only 74 total unforced errors
