Maria Sharapova's career took off after a win at Wimbledon when she was a little girl. After a French Open title a few months ago, she appeared to be back. But her 2012 Wimbledon hopes were derailed in the fourth round on Monday.
The top-seeded Sharapova was defeated by No. 15 seed Sabine Lisicki 6-4, 6-3.
"It's just unbelievable," Lisicki said, according to the AP. "For the third time I've beaten the French Open champion here. I'm just so happy. I've lost the three previous meetings against her. Now I just played well and beat her for the first time."
Also in the women's bracket, No. 6 seed Serena Williams earned a 6-1, 2-6, 7-5 win over Yaroslava Shvedova.
On the men's side, top-seeded Novak Djokovic had no problem in his fourth-round match, while No. 3 seed Roger Federer had some issues.
Djokovic earned an easy 6-3, 6-1, 6-3 win over Viktor Troicki. Federer dealt with a back injury, but was able to secure his 33rd straight Grand Slam quarterfinals appearance with a 7-6 (7-1), 6-1, 4-6, 6-3 win over Xavier Malisse.
"I feel way better than a few hours ago," Federer said after the match. "Honestly, I'm not too worried. I've had bad backs over the years. I just have to keep an eye on it now. ... I hope I'll be 100 percent on Wednesday."
