(KSDK Sports) -- On one of the most surprising days at Wimbledon ever, this may have been the most surprising.

Sergiy Stakhovsky, ranked 116th, knocked out seven-time Wimbledon champion Roger Federer, 6-7, 7-6, 7-5, 7-6.

It was the first time in 21 tries that Stakhovsky had ever beaten a top-10 player.

Stakhovsky called his win "magic," saying, "I couldn't play any better today."

At one point in the match ESPN flashed a graphic showing that Stakhovsky had 12 grass court wins while Federer had 13 grass court titles.

Federer, who had made 36 consecutive major quarterfinals, played poorly at times, shanking a handful of forehand volleys. The winner was masterful with his serve and volley game.

On several points, he got Federer in a position in which he couldn't return a shot or could only return it in a dangerous place.

The day also saw Lleyton Hewitt and Maria Sharapova getting upset and it was a day of injuries and retirement.

Jo-Wilfried Tsonga, Victoria Azarenka and John Isner among the seven players to retire or not start a match due to injuries.

In addition, Caroline Wozniacki lost in straight sets after injuring her ankle early in her match.
