Roger Federer has won nearly a thousand matches in his storied career, so you'll have to forgive him if winning matches just isn't that exciting for him anymore. The last eight times Federer has played the Gerry Weber Open he has advanced to to the final, and he extended that streak to nine straight finals on Sunday when he beat Kei Nishikori 6-3, 7-6 (4) in the semifinals. The funny thing is, Federer had no idea he won.
Locked in a tight second set tiebreaker, Federer had match point at 6-4 and charged the net only to see Nishikori miss the pass into the tape. Federer fist-pumped, wiped the sweat off his brow, and calmly walked back to the baseline for the next point, not realizing he already won the match until he turned around and saw Nishikori waiting for him at the net.
