Querrey-Tsonga marathon suspended by darkness

   Sam Querrey and Jo-Wilfried Tsonga are locked in another Wimbledon marathon.
   Querrey, a San Francisco native seeded 24th, led 6-2, 3-6, 7-6 (5), 1-6, 6-5 today when the third-round match was suspended by darkness after 2 hours, 54 minutes.
   Tsonga, a Frenchman seeded 12th, will serve when the battle resumes on Saturday, not before 5 a.m. PDT, on Court 2 (ESPN). There are no tiebreakers in the fifth set at Wimbledon.
   As another indication of the closeness of the match, Querrey has 52 winners and 27 unforced errors to Tsonga's 51 and 27. Both players have five double faults, but the 6-foot-6 (1.98-meter) Querrey has 22 aces to the 6-foot-2 (1.88-meter) Tsonga's 12. Querrey has won 88 percent of the points on his first serve (69 of 78) to Tsonga's 82 percent (77 of 94).
   Tsonga, 32, is 4-1 against Querrey, 29. But one of the victories went to 14-12 in the fifth set in the second round at Wimbledon in 2014. The encounter lasted 3 hours, 49 minutes.
   Tsonga reached the Wimbledon semifinals in 2011 and 2012 and the quarterfinals there in 2010 and last year.
   Querrey shocked Novak Djokovic in the third round at the All England Club last year en route to the quarterfinals, his best Grand Slam result. Djokovic was ranked No. 1 at the time and had won the past two Wimbledon titles.
   The loss to Querrey marked the beginning of an ongoing tailspin for Djokovic, who has tumbled to No. 4.
   Querrey grew up in Santa Rosa (north of San Francisco), Las Vegas and Thousand Oaks in the Los Angeles area. He now lives in the Los Angeles suburb of Santa Monica.
