Looking in fine form after two days of rest, Roger Federer equaled Jimmy Connors' Open-era record by reaching his 14th Wimbledon quarterfinal and added to his own mark by making it at least that far at a Grand Slam tournament for the 48th time.
Federer, a seven-time champion at the All England Club, has not dropped a set in the tournament through four matches after beating unseeded American Steve Johnson 6-2, 6-3, 7-5 at Centre Court on Monday.
Johnson was making his debut in the fourth round of a major.
The No. 3-seeded Federer hadn't played since Friday, when he was the only man to finish a third-round match. He next faces No. 9 Marin Cilic, the 2009 U.S. Open champion.
Kei Nishikori retired from his fourth-round match against Marin Cilic because of injury.
The fifth-seeded Japanese player was trailing 6-1, 5-1 when he decided to stop the match, giving Cilic a spot in the Wimbledon quarterfinals.
Nishikori warmed up for Wimbledon by playing on grass in Halle, Germany, but he pulled out before his second match because of a rib injury.
Cilic, who will next face either Roger Federer or Steve Johnson in the quarterfinals, won the 2014 U.S. Open title by beating Nishikori in the final.
Anastasia Pavlyuchenkova of Russia reached her first quarterfinal at Wimbledon – and first at any Grand Slam tournament since 2011 – by eliminating CoCo Vandeweghe 6-3, 6-3 on Monday.
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.
Seeking to reach her first major semifinal, Pavlyuchenkova will play either No. 1 Serena Williams or No. 13 Svetlana Kuznetsova next.
Australian Open champion Angelique Kerber advanced to the quarterfinals at Wimbledon by beating Misaki Doi of Japan 6-3, 6-1.
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.
Play is underway under cloudy skies on Day 8 at Wimbledon, kicking off the busiest day in Grand Slam tennis.
Play began on schedule on the outside courts at 11: 30 a.m., with matches on Centre Court and No. 1 Court set to begin at 1 p.m.
The forecast is for dry conditions, with temperatures reaching 21 degrees C (70 degrees F).
Week 2 of Wimbledon starts with the busiest day in Grand Slam tennis, with all 16 men's and women's fourth-round matches on Monday's schedule.
After rain delays forced organizers to schedule matches on the middle Sunday for only the fourth time in history, the tournament is back on track going into the second week.
Seven-time men's champion Roger Federer is scheduled first on Centre Court, facing 29th-ranked Steve Johnson.
Six-time women's winner Serena Williams is paired against Svetlana Kuznetsova in the next match on Centre Court, followed by No. 2 Andy Murray against Nick Kyrgios.
Missing from the schedule is No. 1 Novak Djokovic, whose 30-match Grand Slam-winning streak was snapped by Sam Querrey in the third round on Saturday.
