LONDON, July 4 (Reuters) - A streaker failed to distract Maria Sharapova and the other top women's seeds also marched through to their allotted places in the Wimbledon semi-finals on Tuesday.
Fourth seed Sharapova, the 2004 champion, beat fellow Russian Elena Dementieva 6-1 6-4 while top seed Amelie Mauresmo, second seed Kim Clijsters and number three Justine Henin-Hardenne won their quarter-finals.
Clijsters ended China's hopes of a first grand slam singles semi-finalist when she overcame Li Na 6-4 7-5 and will face Belgian compatriot Henin-Hardenne in the last four.
Henin-Hardenne, who beat Clijsters in the semi-finals of both the French Open and the pre-Wimbledon Eastbourne event last month, was a 6-4 6-4 winner over French qualifier Severine Bremond.
Mauresmo will face Sharapova after surviving a determined challenge from another Russian, Anastasia Myskina. The Australian Open champion came through 6-1 3-6 6-3.
Sharapova's head was not for turning on Centre Court. She was 6-1 and 3-0 up when a naked man ran on to the playing area and performed a cartwheel in front of her.
Security eventually bundled him off, and after losing three successive games, Sharapova recovered her composure to finish off Dementieva.
"It was real bizarre," said Sharapova, who is through to her third successive Wimbledon semi-final. "Even more bizarre that it took 10 seconds for security to come out." "It was real bizarre,'' fourth-seeded Sharapova said in her post-match news conference. "I didn't really look at the guy, thank God. I didn't want to look.''
Wimbledon's All England Club said later it would review its safety procedures
