Days after Rafael Nadal was upset in the first round of Wimbledon, seven-time champion Roger Federer suffered a stunning defeat today, losing in round two of Wimbledon to the 116th ranked player in the world.

27-year-old Ukrainian Sergiy Stakhovsky outplayed Federer on Centre Court, defeating the #3 ranked defending Wimbledon champion 6-7 (5), 7-6 (5), 7-5, 7-6 (5) in one of the more stunning upsets, not only the tournament's history, but in Grand Slam history.

The defeat marks the earliest exit for Federer at the All England Club, and his earliest exit from a Grand Slam tournament in over a decade.

Federer's loss wasn't the only surprise at Wimbledon today. Seven players exited the tournament Wednesday by withdrawals or midmatch retirements, marking the most in one day at a Grand Slam tournament in the 45-year Open era.

Players who withdrew include the following: Second-seeded female Victoria Azarenka, sixth-seeded male Jo-Wilfried Tsonga, Steve Darcis (who upset Rafael Nadal in the first round), American John Isner,  10th-seeded male Marin Cilic, 2006 male quarterfinalist Radek Stepanek; and female star Yaroslava Shvedova.
