LONDON (AP) The Latest from Wimbledon (all times local):
Novak Djokovic says he will not play in the Davis Cup quarterfinals against Britain this month.
Djokovic says he wasn't 100 percent healthy while losing to Sam Querrey in the third round at Wimbledon on Saturday, but wouldn't say what was wrong.
When asked if he would play against Britain from July 15-17 in the best-of-five series, Djokovic said: ''No, I'm not going to play Davis Cup.''
Serbia won the Davis Cup in 2010.
Play is done for the day at Wimbledon, with four men's third-round matches suspended in progress Saturday night.
That includes No. 7 Richard Gasquet leading Albert Ramos-Vinolas, No. 18 John Isner leading No. 12 Jo-Wilfried Tsonga, and No. 32 Lucas Pouille leading 2009 U.S. Open champion Juan Martin del Potro - all by two sets to one.
No. 15 Nick Kyrgios and No. 22 Feliciano Lopez are even at a set apiece.
Action will resume Sunday - only the fourth time in 139 years that Wimbledon has scheduled matches on the middle Sunday because of rain during the first week.
Lleyton Hewitt's delayed retirement just got delayed a little bit more.
The 2002 singles champion at Wimbledon teamed up with Jordan Thompson to beat Nicolas Almagro and David Marrero of Spain 6-7 (6), 6-4, 19-17 in doubles.
The match lasted nearly four hours and finally ended with Hewitt holding serve.
Hewitt finished his singles career at the Australian Open, but then accepted a wild-card entry into the men's doubles tournament at Wimbledon.
Ninth-seeded Madison Keys advanced to the fourth round at Wimbledon by beating Alize Cornet 6-4, 5-7, 6-2 on No. 1 Court.
The American player, who reached the quarterfinals at the All England Club in 2015, last week became the first American woman to make her debut in the top 10 since Serena Williams in 1999.
Keys came into Wimbledon after winning a grass-court title in Birmingham.
Andy Murray made his way into the fourth round at Wimbledon by beating John Millman of Australia 6-3, 7-5, 6-2.
Murray, the 2013 champion at the All England Club, played his match on Centre Court, starting with the roof open but finishing with it closed after a rain delay.
Murray has lost to Novak Djokovic in the finals of both the Australian Open and French Open this year. With Djokovic losing Saturday, the second-seeded Murray could face seven-time champion Roger Federer in the final.
Former Wimbledon champion Petra Kvitova lost Saturday at the All England Club.
The 10th-seeded Czech player lost to Ekaterina Makarova of Russia 7-5, 7-6 (5) in the final second-round match of the tournament.
Kvitova and Makarova started the match on Friday, but rain suspended play. After several delays on Saturday, Makarova was finally able to close out the match and the second round.
Kvitova won the Wimbledon title in 2011 and `14. Makarova's best showing at Wimbledon was a quarterfinal appearance in 2014.
Novak Djokovic's 30-match Grand Slam winning streak is over after a stunning 7-6 (6), 6-1, 3-6, 7-6 (5) loss to 41st-ranked Sam Querrey in Wimbledon's third round.
Djokovic had won the past four major titles in a row - and was halfway to the first calendar-year Grand Slam for a man since Rod Laver's in 1969.
The match ended Saturday, when it was interrupted by three rain delays.
They began playing Friday, when Querrey grabbed a two-set lead before play was suspended by showers.
When they resumed Saturday, two-time defending Wimbledon champion Djokovic quickly took a 5-0 lead en route to winning the third set, and then he served for the fourth at 5-4. But he was broken there, and they headed to a tiebreaker. The match closed on a forehand error by Djokovic.
Novak Djokovic and Sam Querrey are back out on court after their third rain delay of the day.

Organizers decided to play on Sunday for only the fourth time in the tournament's 139-year history after severe delays because of rain.
Kei Nishikori has reached the fourth round at Wimbledon and equaled his best performance at the All England Club.
Nishikori beat Andrey Kuznetsov of Russia 7-5, 6-3, 7-5 in less than two hours. He made only 14 unforced errors.
That set up Nishikori against Marin Cilic, who beat the Japanese star in the 2014 U.S. Open final.
Since then, Nishikori has won both of his matches with the Croat, both last year on outdoor hard courts. Their fourth-round match will be their first on grass.

Alexander Zverev finished off his match on Saturday, and finally completed the men's second round at Wimbledon.

There is one more second-round match still to be completed, between two-time champion Petra Kvitova and Ekaterina Makarova.

The top-seeded Djokovic, a three-time Wimbledon champion, won the third set of his match against Sam Querrey 6-3.

Serena Williams and Viktor Troicki each have been fined $10,000 at Wimbledon for unsportsmanlike conduct.
The penalties were announced on Saturday at the Grand Slam tournament, where the biggest amount deducted from a player's paycheck so far is the $12,000 for Britain's Heather Watson, also for unsportsmanlike conduct.
The No. 1-seeded Williams' fine was from her second-round victory on Friday. She smashed her racket repeatedly against the turf while sitting in her sideline chair after dropping the first set against Christina McHale, then flung the piece of equipment so far behind her that it landed in the lap of a TV cameraman.
Troicki, a Serb seeded 25th, was punished for his tirade against the chair umpire at the end of a five-set loss on Thursday.
Wimbledon organizers say they will sell 10,000 unreserved tickets for Sunday's play on Centre Court at the All England Club, and 8,000 for No. 1 Court.

Wimbledon says all tickets will be available only online. Centre Court tickets will cost 70 pounds ($93), while No. 1 Court tickets will be 40 pounds ($53) and grounds passes will be 20 pounds ($27).
The only other times that tournament organizers opted to have play on the middle Sunday were 1991, 1997 and 2004. Each time, the occasion - dubbed ''People's Sunday'' - created a carnival-like atmosphere, with the normally staid grounds filled with rowdy fans who snapped up tickets they rarely get the opportunity to buy.

High noon comes for Novak Djokovic when he resumes his third-round match at Wimbledon two sets down against Sam Querrey of the United States on Saturday.
Querrey leads 7-6 (6), 6-1 after their match was one of eight suspended overnight because of rain.
He threatens to end Djokovic's bid for a true Grand Slam. Djokovic has won the past four major titles, but no man has won them all in the same year since Rod Laver in 1969.
Also in action Saturday is 2013 Wimbledon champion Andy Murray, who will try to join Roger Federer in the fourth round.
There are also three Wimbledon women's runners-up on the schedule: Agnieszka Radwanska, Sabine Lisicki, and Eugenie Bouchard.
