Tursunov aggravates injury, quits French Open match

   Dmitry Tursunov had gotten off to a good start in the French Open.
   A 30-year-old Russian based in the Sacramento suburb of Granite Bay, Tursunov had upset 22nd-seeded Alexandr Dolgopolov in straight sets in the first round in Paris.
   On Thursday, the 60th-ranked Tursunov met No. 54 Victor Hanescu of Romania in the second round. Tursunov, who led the head-to-head series 3-1, trailed 4-6, 6-6 (1-3) when he retired after aggravating a pulled left hamstring muscle.
   Tursunov suffered the injury three weeks ago in Rome in his last practice for the Italian Open and retired from his first-round qualifying match. The Hanescu match was Tursunov's first since then.
   In an e-mail, Tursunov said he expects to be out for three more weeks and play Wimbledon, which begins June 24. He reached the fourth round at Wimbledon in 2005 and 2006 for his best Grand Slam singles results to date.
   Eighteenth-seeded Sam Querrey, a San Francisco native and part-time member of the Sacramento Capitals in World TeamTennis, is scheduled to face 15th-seeded Gilles Simon of France today in the third round. It's the first time Querrey has advanced that far in the French Open in seven appearances.
   Former Stanford star Mallory Burdette, playing in her first French Open, lost to fourth-seeded Agnieszka Radwanska of Poland 6-3, 6-2 on Wednesday in the second round.
   Burdette also lost in the first round of doubles, as did 2003 NCAA doubles champion Raquel Kops-Jones from Cal and ex-Stanford star Scott Lipsky. Burdette played with Sloane Stephens, Kops-Jones was seeded sixth with fellow Californian Abigail Spears, and Lipsky was seeded 11th with Santiago Gonzalez of Mexico.
  Top-ranked Bob and Mike Bryan, the 1998 NCAA doubles champs from Stanford, are scheduled to face Eric Butorac and Jack Sock on Saturday or Sunday in an all-American matchup in the second round.
