LONDON (AP) The Latest on Wimbledon (all times local):
Two-time major champion Svetlana Kuznetsova put aside a warning for getting coached and erased a big deficit in the third set to edge 18th-seeded Sloane Stephens 6-7 (1), 6-2, 8-6 in the third round at Wimbledon.
Back in the fourth round at the All England Club for the first time since 2008, the 13th-seeded Kuznetsova will meet No. 1 Serena Williams for a quarterfinal berth.
Kuznetsova, who won the 2004 U.S. Open and 2009 French Open, needed nearly 2 1/2 hours to get past Stephens.
Early in the third set, Kuznetsova argued with chair umpire Mariana Alves about whether she was receiving help from her coach, which is not allowed at Grand Slam matches.
Then, Stephens served for the match at 5-3 but Kuznetsova broke, part of a stretch in which she took five of the last six games.
Defending champion Serena Williams did not need to work too hard to earn her 300th career Grand Slam match win and move into the fourth round at Wimbledon, overwhelming 43rd-ranked Annika Beck of Germany 6-3, 6-0.
It took all of 51 minutes at Centre Court on Sunday.
Williams, who has won six of her 21 Grand Slam titles at the All England Club, compiled a 25-2 edge in winners.
After falling behind 2-1 at the outset against Beck, Williams won 11 of the last 12 games and 24 of the second set's 28 points.
The No. 1-ranked Williams improved to 300-42 at major tournaments. That breaks a tie at 299 wins with Chris Evert and now ranks second in the Open era to Martina Navratilova, who went 306-49.
Anastasia Pavlyuchenkova has reached the fourth round at Wimbledon for the first time.
The 23rd-seeded Russian beat No. 11 Timea Bacsinszky of Switzerland 6-3, 6-2 on Sunday.
Bacsinszky made it to the quarterfinals last year, but failed to break serve once on Sunday.
She'll next face Coco Vandeweghe, who beat No. 7 Roberta Vinci in straight sets.
Coco Vandeweghe is making a strong run at Wimbledon for the second year in a row.
The 27th-seeded American beat No. 7 Roberta Vinci of Italy 6-3, 6-4 on Centre Court on Sunday to reach the fourth round.
Vandeweghe advanced to the quarterfinals here last year before losing to Maria Sharapova in three sets. This is the first time she's been seeded at a Grand Slam.
Play is underway on Day 7 at Wimbledon, only the fourth time in the tournament's 139-year history that matches are being played on the middle Sunday.
Sixth-seeded Roberta Vinci opened play on Centre Court against Coco Vandeweghe of the United States in a third-round match. No. 13 Svetlana Kuznetsova faced No. 18 Sloane Stephens on Court No. 1.
Play began under gray skies, but the forecast called for mainly dry conditions and warmer temperatures reaching 22C (72F).
For only the fourth time in the tournament's 139-year history, the middle Sunday at Wimbledon is not a day for rest.
With rain delays during the first week forcing organizers to schedule Sunday matches for the first time since 2004, all 22,000 tickets were snapped up in 27 minutes when they went on sale online on Saturday.
Fans will get to see top-seeded and six-time women's champion Serena Williams, who plays in the day's second match on Centre Court against Germany's Annika Beck. The winner will move into the fourth round.
The tournament is still reverberating from the stunning exit of Novak Djokovic, whose bid for a fifth consecutive major title and the third leg of a calendar-year Grand Slam was stopped by American Sam Querrey in the third round.
