He finished the match with 45 unforced errors _ 29 with his forehand _ and only 13 winners, to 35 unforced errors and 34 winners by Andreev.

Nadal turned his ankle in the opening set against Grosjean and took a timeout, but didn't show any significant effects of the injury the rest of the match.

Afterward, he pulled out of the doubles competition, saying that was a precautionary move and that he believes his ankle is going to be OK for his next match. He's not scheduled to play Thursday.

A day after ousting two-time winner Lindsay Davenport, Hingis impressed against 10th-seeded Safina with her shot placement and footwork.

"So far, so good. I'm definitely very happy with the progress I'm making," Hingis said. "Today probably wasn't my prettiest game, but it was effective.

"Now I've got a day of rest, and will see what I can do in the semifinals."

Hingis ended a three-year retirement in January, and has run her match record to 20-6. She said she considers her comeback as "pretty much over with now."

"It's just more because this is my first American tournament that people look it at still as a comeback," she said.

Also advancing on the men's side were Paradorn Srichaphan, who beat fourth-seeded David Nalbandian 6-7 (5), 6-3, 6-2 and will play Jarkko Nieminen of Finland, a 6-4, 6-3 winner over Marat Safin; Ljubicic after beating fellow Croatian Mario Ancic 6-3, 6-4; and Baghdatis, who defeated Tomas Berdych of the Czech Republic 6-4, 6-1. Ivan Ljubicic downed fellow Croatian Mario Ancic 6-3, 6-4; and Jarkko Nieminen beat Marat Safin 6-4, 6-3.
