London, England - Top seed Novak Djokovic and reigning champion Andy Murray highlighted Monday's fourth-round winners at The Championships, Wimbledon.
A rainy day saw the former champion Djokovic handle 14th-seeded Frenchman Jo- Wilfried Tsonga 6-3, 6-4, 7-6 (7-5) under the roof on the famed Centre Court. The brisk match came to a close in 1 hour, 52 minutes when the return-of-serve artist Djokovic smacked a cross-court, two-handed backhand winner that just caught the line to seal the deal.
Djokovic popped 14 aces and was not broken in the bout, while Tsonga struck 19 aces, but was broken twice by the Serbian stalwart.
The 27-year-old Djokovic has now won his last 18 sets against Tsonga, who also lost to the Serbian star in the 2008 Australian Open final.
The recent French Open runner-up Djokovic titled here in 2011 and was last year's Wimbledon runner-up to Murray. The Serb has reached at least the quarterfinals here six years running.
His quarterfinal opponent will be Croat Marin Cilic.
The third-seeded Murray reached a seventh straight Wimbledon quarterfinal by getting past 20th-seeded 6-foot-8 South African Kevin Anderson 6-4, 6-3, 7-6 (8-6) in 2 hours, 33 minutes, also under the roof on Centre Court, as wet weather forced the issue on Day 7 of the fortnight.
The roof was open when the match started and closed during the second set.
"When it was outdoors, I played very well and was in a good position. When we came back indoors, he started to strike the ball a bit better, he started serving better," Murray said.
"It's a good win because he was playing well at the end and making it very tough for me. It's good to get through in straight sets."
The match was watched by the likes of Virgin tycoon Richard Branson, pop singer Cliff Richard and two-time 1970s Wimbledon finalist Ilie Nastase in a striking Romanian army uniform.
Murray has now won his last 17 matches at the AEC, where be captured an Olympic gold medal in 2012 and gave Britain its first male Wimbledon singles champion in 77 years a year ago.
The 27-year-old Scot, who has yet to drop a set thus far, hasn't titled anywhere since capturing the Wimbledon title last July.
His quarterfinal opponent on Wednesday will be rapidly rising 11th-seeded Bulgarian Grigor Dimitrov, who reached his first-ever Wimbledon quarter by getting past unseeded Argentine Leonardo Mayer 6-4, 7-6 (8-6), 6-2 in between rain drops on Monday.
The 23-year-old Dimitrov captured his first-ever grass-court title at The Queen's Club in London a few weeks ago and is a perfect 8-0 on grass this year.
Australian Open champion Stan Wawrinka beat Uzbekistan's Denis Istomin 6-3, 6-3, 6-4 to reach the fourth round. The fifth-seeded Swiss slugger tallied 12 aces among his 33 winners, broke Istomin's serve four times and saved all three break points against him in a match that was postponed because of rain on Saturday.
Wawrinka will face in-form Spaniard Feliciano Lopez in the round of 16. The 19th-seeded Lopez took out ninth-seeded John Isner, 6-7 (8-10), 7-6 (8-6), 7-6 (7-3), 7-5. Isner was the last American standing in the men's draw.
Lopez and the 6-foot-10 Isner combined for a whopping 86 aces, including 52 by the towering American.
For the first time since 1911, there are no Americans, male of female, playing in the fourth round at Wimbledon.
The left-handed Lopez has been on fire on grass, going 12-1 on the surface this year, including a title in Eastbourne two weeks ago and a runner-up finish at The Queen's Club in London the week before that.
The 26th-seeded Cilic became the first man to reach the quarterfinals on Monday by handling France's Jeremy Chardy, 7-6 (10-8), 6-4, 6-4.
Cilic will appear in his fourth career Grand Slam quarterfinal (1-2).
Kei Nishikori reached the fourth round by completing a five-set victory over Italian Simone Bolelli. The 10th seed from Japan claimed a 3-6, 6-3, 4-6, 7-6 (7-4), 6-4 victory to arrange a meeting with eighth-seeded Canadian Milos Raonic.
Nishikori-Bolelli was suspended because of rain on Saturday with the two tied at 3-3 in the deciding set.
In some more fourth-round action on Tuesday, second-seeded world No. 1 Rafael Nadal will face upstart Aussie Nick Kyrgios; fourth-seeded former No. 1 Roger Federer will take on 23rd-seeded Spaniard Tommy Robredo; Wawrinka will tangle with Lopez; and Raonic will lock horns with Nishikori.
The 14-time Grand Slam winner Nadal is the reigning French and U.S. Open champ who is also a two-time Wimbledon titlist, while the 17-time major champion Federer is a seven-time Wimbledon champ.
