Federer, Murray, Serena reach Wimbledon last eight, bad light halts Djokovic and Anderson

Seven-time champion Roger Federer, local hero Andy Murray and 20-time Grand Slam winner Serena Williams reached the Wimbledon quarterfinals here on Monday but the match between defending champion Novak Djokovic and Kevin Anderson was suspended until Tuesday at two sets apiece.

Roger Federer, 33, took just an hour and 25 minutes to defeat Spain's Roberto Bautista Agut 6-2, 6-2, 6-3 to move into the Wimbledon last eight for a 13th time.

"It was nice to play a baseliner after two big servers. I did a nice job making the transition," said Federer, who overcame Sam Querrey and Sam Groth in the previous rounds.

"Clearly I felt I had more time on the return (and was) still able to play aggressive tennis, committed on the return as well. It was a good match. I got off to a good start and kept rolling."

The second seed will next take on Frenchman Gilles Simon, who Federer has defeated five times in seven meetings. Simon advanced with an upset of Tomas Berdych.

Murray, the third seed, is through to his 18th consecutive Grand Slam quarterfinal -- and his eighth at Wimbledon -- after beating Croatian Ivo Karlovic 7-6 (7), 6-4, 5-7, 6-4.

The Scot will fight for a semifinal berth against unseeded Canadian Vasek Pospisil, who became only the third Canadian man to reach quarterfinals by beating Serbia's Viktor Troicki.

Djokovic looked very likely to become the first top seed since Pete Sampras in 2001 to lose in the fourth round, dropping the first two sets 6-7 (6), 6-7 (6) after almost two hours.

But the world No. 1 made a strong comeback to win the next two sets 6-1, 6-4. When the daylight gave out after three hours of play, the match was suspended on Court One with the last set to be played on Tuesday.

The winner will face last year's US Open champion Marin Cilic for a place in the last four.

French Open champion Stan Wawringka defeated Belgium's 16th seed David Goffin 7-6 (3), 7-6 (7), 6-4 to reach the last eight for the second successive year. He will next take on French 21st seed Richard Gasquet, who beat Australian Nick Kyrgios 7-5, 6-1, 6-7 (7), 7-6 (6).

In the women's action, No.1 seed Serena beat 16th-seeded sister Venus Williams 6-4, 6-3 in 68 minutes and took her career tally against Venus to 15-11 after their first Wimbledon meeting in six years.

"It's hard to feel excited beating someone you root for all the time and you love and is your best friend in the whole world," said Serena. "But you play in the moment. I think I served well, not huge except for one big one. I was consistent with my serve. She was playing really well."

Spain's Garbine Muguruza shocked No.5 seed Caroline Wozniacki 6-4, 6-4 to reach the quarterfinals for the first time.

"It means a lot because I didn't play a lot of matches on grass, so I didn't know how to kind of prepare for Wimbledon," she said. "I think it's like the third time I play. So for me was something new. That's why it's special."

Sharapova reached the quarterfinals for the first time since 2011 after beating Kazakhstan's Zarina Diyas 6-4, 6-4. The No. 4 seed will face unheralded American CoCo Vandeweghe on Tuesday as she continues her bid for a second Wimbledon title.

Poland's Agnieszka Radwanska beat Serbia's Jelena Jankovic 7-5, 6-4, American Addison Keys fought from one set down to defeat Olga Govortsova of Belarus 3-6, 6-4, 6-1, former world No. 1 Victoria Azarenka of Belarus eased past Swiss Belinda Bencic 6-2, 6-3, 15th seed timea Bacsinszky of Switzerland beat Romanian Monica Niculescu 1-6, 7-5, 6-2.
