WIMBLEDON, England -- In the final game, a desperate Maria Sharapova lunged to hit one shot left-handed, and twice challenged calls but lost. Then she lost the match as well.

Sharapova won seven consecutive games during one stretch but let a late lead slip away Wednesday and was beaten by Gisela Dulko, 6-2, 3-6, 6-4 in the second round at Wimbledon.

In a wild, 14-point final game, Sharapova saved four match points. But on the fifth she pushed an easy forehand long, and she was out of the tournament after two rounds for the second year in a row.

The 2004 champion was playing in her fourth event since rejoining the tour last month following shoulder surgery in October. She's ranked 60th but was seeded 24th because of past success at the All England Club.

"This is not an overnight process," Sharapova said. "It's going to take time, as much time as I need on the court, to get everything together. ... Just being here is a wonderful accomplishment."
