Serena Williams moves to second all-time in Slam wins

— -- 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.

The victory pushed Williams past Chrissie Evert into second for career Slam victories in the Open era. Williams trails only Martina Navratilova, who went 306-49 in her career.

It took all of 51 minutes at Centre Court on Sunday for Williams to advance. 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 final 12 games and 24 of the second set's 28 points.

The No. 1-ranked Williams improved to 300-42 at major tournaments.

Williams will next face two-time major champion Svetlana Kuznetsova, who 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.

Kuznetsova, who won the 2004 US Open and 2009 French Open, needed almost 2½ 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.

Stephens served for the match at 5-3, but Kuznetsova broke, part of a stretch in which she took five of the final six games.

Also, 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.

Pavlyuchenkova will next face No. 27 Coco Vandeweghe, who beat No. 7 Roberta Vinci 6-3, 6-4 to improve to 4-0 vs. top-10 players this season.
