LONDON — As the rain wreaks havoc on the Wimbledon schedule and players start to complain, Andy Murray and Novak Djokovic have found little reason to worry about the weather.
It helped that both got to play Monday on Centre Court, the only spot at the All England Club with a retractable roof.
And with straight-set victories, they moved closer to a semifinal version of last year's final when Murray beat Djokovic to become the first British man since 1936 to win Wimbledon.
Murray reached the quarterfinals for the seventh straight year by saving a set point in the tiebreaker to defeat 20th-seeded Kevin Anderson 6-4, 6-3, 7-6 (8-6). They played under a drizzle for about 15 minutes before the roof was closed early in the second set.
It stayed that way for top-seeded Djokovic, and the 2011 champion beat No. 14 Jo-Wilfried Tsonga for the 11th consecutive time, 6-3, 6-4, 7-6 (7-5). Djokovic grimaced once in the final set while clutching the upper left arm he landed on in his prior match, but he said afterward he felt fine.
The start of Week 2 at Wimbledon is called "Manic Monday," because it usually has all 16 fourth-round matches after taking Sunday off. Australian Open champion Stan Wawrinka was displeased that his third-round match was put off from Saturday to Monday. He beat No. 45 Denis Istomin 6-3, 6-3, 6-4 in less than 90 minutes.
"(Wimbledon officials) just say what's going to be the schedule and that's it,'' Wawrinka said. "Even if you want to talk to them, they're not going to change anything. They don't listen (to) the player. They just do what they think is good for them."
Wawrinka plays today against No. 19 Feliciano Lopez, who eliminated the last American singles player, Tampa resident John Isner, 6-7 (8-10), 7-6 (8-6), 7-6 (7-3), 7-5. It's the first time in 103 years that no U.S. men or women reached the round of 16.
Maria Sharapova's fourth-round match against No. 9 Angelique Kerber was rescheduled for today. The winner plays Wednesday against No. 13 Eugenie Bouchard, the first Canadian in the quarterfinals in the Open era. Bouchard advanced with a 7-6 (7-5), 7-5 win over No. 25 Alize Cornet, who beat Serena Williams on Saturday.
