Querrey advances, teen Anisimova loses in BNP

   No. 18 seed Sam Querrey, a 30-year-old San Francisco native, outlasted qualifier Yuki Bhambri of India 6-7 (4), 6-4, 6-4 today in the third round of the BNP Paribas Open at Indian Wells.
   The 6-foot-6 (1.98-meter) Querrey hammered 17 aces and won 83 percent of the points on his first serve (40 of 48) in the 2-hour, 22-minute match.
   Querrey equaled his best result at Indian Wells in his 13th appearance. He also reached the fourth round in 2011 and 2013.
   Querrey is scheduled to play No. 28 seed Feliciano Lopez of Spain for a quarterfinal berth on Wednesday not before 6 p.m. PDT (Tennis Channel) in 8,000-seat Stadium 2.
   Lopez, a 36-year-old left-hander, held off No. 8 Jack Sock of Kansas City, Kan., 7-6 (6), 4-6, 6-4 in a 2-hour, 25-minute night match in Stadium 1.
   Lopez leads Querrey 6-4 in their head-to-head series, but Querrey won the last meeting 6-3, 6-4, 6-2 in the first round of the Australian Open in January.
   In the women's fourth round at Indian Wells, fifth-seeded Karolina Pliskova of the Czech Republic downed 16-year-old U.S. phenom Amanda Anisimova 6-1, 7-6 (2).
   Anisimova, who won the $60,000 Sacramento Challenger last July, had beaten No. 9 seed and two-time Wimbledon champion Petra Kvitova in the third round. Anisimova ended Kvitova's winning streak at 14 matches.
   No. 7 seeds Bob and Mike Bryan, former Stanford stars and two-time Indian Wells champions, dismissed Spaniards Pablo Carreno Busta and David Marrero 6-2, 6-3 to reach the quarterfinals.
   Obituary -- Ken Flach, who ascended to No. 1 in the world in doubles in 1985, died from complications of pneumonia on Monday in San Francisco at age 54.
   Flach, a St. Louis native who lived in Mill Valley in the San Francisco Bay Area, won six Grand Slam titles (four in men's doubles and two in mixed doubles) and claimed the men's doubles gold medal at the 1988 Olympics in Seoul with longtime partner Robert Seguso.
