PARIS, June 4 (UPI) -- Top seed Amelie Mauresmo and No. 4 Maria Sharapova both lost their fourth round matches Sunday at the French Open Tennis Tournament in Paris.
Before a home crowd, Mauresmo, the No. 1 women's singles player in the latest rankings, was beaten by 16th-seeded Nicole Vaidisova of the Czech Republic, 6-7 (5-7), 6-1, 6-2.
Sharapova was knocked off by No. 14 Dinara Safina, also from Russia, 7-5, 2-6, 7-5.
"I had a little feeling of exhaustion in the second and third sets and (Vaidisova) was serving much better than me while I was not able to hold my serve," Mauresmo said.
"(Safina) picked up her game a little bit and mine went down, and that's not a good combination," said Sharapova, who made 63 unforced errors.
Second-seed Kim Clijsters of Belgium, 13th-seed Anna-Lena Groenefeld of Germany and No. 11 Venus Williams of the United States won their matches Sunday.
