NEW YORK — Grit was not going to be enough to get Maria Sharapova through this one.
Not with nine double-faults, including three in a row.
Not with a total of 36 unforced errors.
And certainly not with No. 1-seeded Caroline Wozniacki of Denmark across the net Monday in the fourth round of the U.S. Open, doing "what she does best," as Sharapova herself put it: getting to nearly every ball and hammering it back, stretching points on and on and on until her opponent misses the mark.
It added up to a 6-3, 6-4 victory for 2009 U.S. Open runner-up Wozniacki over Sharapova, who has failed to make it even as far as the quarterfinals at Flushing Meadows since winning the 2006 title.
"I felt like I was playing well out there," Wozniacki said, then made sure everyone understood a key concept by adding, "I made her do those errors."
It's the first victory for Wozniacki in three career meetings against Sharapova, but they hadn't met since 2008.
Wozniacki carries a 12-match winning streak into her quarterfinal against 45th-ranked Dominika Cibulkova, who eliminated 2004 U.S. Open champion Svetlana Kuznetsova 7-5, 7-6 (4).
Third-seeded Novak Djokovic might have said the same about his own play Monday, when he reached the men's quarterfinals at the U.S. Open for the fourth consecutive year by outclassing No. 19 Mardy Fish 6-3, 6-4, 6-1. Fish's exit leaves one U.S. man in the tournament, No. 20 Sam Querrey, who is in fourth-round action today against No. 25 Stanislas Wawrinka of Switzerland.
Djokovic, the 2007 U.S. Open runner-up and 2008 Australian Open champion, next faces No. 17 Gael Monfils, a 6-4, 7-5, 7-5 winner over Richard Gasquet in an all-French matchup.Another quarterfinal will pit five-time U.S. Open champion Roger Federer against No. 5 Robin Soderling, a two-time French Open finalist whose upset of Federer in that round at Paris this year ended his record streak of reaching the semifinals at 23 consecutive Grand Slam tournaments.
Federer reached the quarterfinals at a 26th major in a row by beating No. 13 Jurgen Melzer of Austria 6-3, 7-6 (4), 6-3 in Monday night's last match.
Sweden's Soderling hit 15 aces and did not face a single break point after the first set of his 4-6, 6-3, 6-2, 6-3 win against No. 21 Albert Montanes of Spain.
