LONDON — After recovering from a fall on the slick turf, and a brief deficit, Serena Williams reeled off the last nine games to reach the Wimbledon quarterfinals Monday.
The defending champion dominated down the stretch once the Centre Court roof was closed and eliminated two-time major title winner Svetlana Kuznetsova 7-5, 6-0. Williams won 24 of 29 points in the second set and finished with a 43-8 advantage in winners.
The No. 1-seeded American slipped during a point while she was getting broken to trail 5-4 in the opening set of the fourth-round match. Kuznetsova then served for that set, but Williams broke right back to make it 5-all. That’s when play was delayed for nearly 30 minutes while the retractable roof was shut.
After they resumed, Kuznetsova did not take a game.
Seeking her seventh Wimbledon title and 22nd Grand Slam trophy overall, Williams next faces 21st-seeded Anastasia Pavlyuchenkova of Russia. Pavlyuchenkova of Russia reached her first Wimbledon quarterfinals — and first at any Grand Slam tournament since 2011 — by eliminating CoCo Vandeweghe 6-3, 6-3.
Earlier Monday, third-seeded Agnieszka Radwanska fell to Dominika Cibulkova 6-3, 5-7, 9-7 in the fourth round and Australian Open champion Angelique Kerber advanced to the quarterfinals by beating Misaki Doi of Japan 6-3, 6-1.
The 21st-seeded Pavlyuchenkova had only seven unforced errors, 15 fewer than No. 27 Vandeweghe, and broke the American five times. Vandeweghe, a 2015 quarterfinalist at the All England Club, had lost serve only twice in the first three rounds this year.
Radwanska, a finalist at the All England Club in 2012, struggled at this year’s tournament. In the second round, she had to save three match points before beating Ana Konjuh in three sets.
She also saved match points against Cibulkova — one in the second set — and wasted a match point in the third.
The 18th-seeded Cibulkova reached the Wimbledon quarterfinals once before, in 2011. Her best result at a Grand Slam tournament came in 2014, when she reached the Australian Open final, losing to Li Na.
Kerber, a German seeded fourth, reached the semifinals at the All England Club in 2012 and also made the quarterfinals in 2014. Last year, she lost in the third round.
Kerber won her first major title this year, beating Serena Williams in the Australian Open final. If Kerber wins the Wimbledon title and Williams fails to reach the semifinals, she would take over the No. 1 ranking.
