What an unusual score line for Mary?! 4-6 6-0 6-0...
Not sure what happened here...
Can't be sure if Mary had an injury or just wasn't in the zone.
Well done Li, it was a great win
Dont give up, Mary - the road back from injury sometimes is a tough one and you did real well to win through to 3rd round after so little competitive play this year
Here is a comment after the match...
NEW YORK, Sept. 4 (Xinhua) -- Li Na came out the first Chinese woman to reach the last 16 of the U.S. Open here on Sunday after upsetting last year's runner-up Mary Pierce 4-6, 6-0, 6-0.
"I'm not nervous. I'm excited," said the 24-year-old, who came back to sweep the last 12 games to seal victory after losing the first set to the 13th-seeded French veteran.
Li, having battling injuries this season, blasted 51 winners to just 14 for Pierce though committing 22 unforced errors in the opening set, and turned to make only three errors in a near-perfect second set to turn the match around.
"I was hitting the ball short and my opponent played very good. She served well and hit the ball hard and deep. She didn't give me much of a chance," said Pierce, runner-up at Flushing Meadows last year to Kim Clijsters.
