Sidelines: Venus, Halep win; Wozniacki upset by Kasatkina at Indian Wells.
INDIAN WELLS, Calif. — Venus Williams defeated Anastasija Sevastova of Latvia 7-6 (8), 6-4 to reach the quarterfinals of the BNP Paribas Open on Tuesday as the oldest woman in the draw.
The 37-year-old American was coming off a straight-set victory over younger sister Serena a night earlier, ending a threematch skid against her sibling.
Playing under cloudy skies in 80-degree heat, Williams had her hands full with Sevastova, who used drop shots, top spin, lobs and jerked her 10-years-older opponent side to side.
After early losses in her first two tournaments of the year, Williams hasn’t dropped a set at Indian Wells, where she has yet to reach the final in six previous appearances.
Awaiting Williams in the quarterfinals is 27th-seeded Carla Suarez Navarro of Spain, who beat American wild card Danielle Collins 6-2, 6-4.
Simona Halep is on track to retain her No. 1 world ranking after defeating Wang Qiang of China 7-5, 6-1 in the fourth round.
Halep is the only former Indian Wells winner left in the women’s draw after No. 20 Daria Kasatkina upset No. 2 Caroline Wozniacki 6-4, 7-5. Wozniacki blew a 3-0 lead in the first set and was on the run most of the match before losing for the second time this year to the 20-year-old Russian.
By reaching the quarterfinals, Kasatkina is projected to surpass her career-best ranking of 17th. She has beaten all four current Grand Slam titleholders in the past year, including U.S. Open winner Sloane Stephens in straight sets this week.
On the men’s side, Gael Monfils retired in the second set with a back injury trailing fellow Frenchman Pierre-Hughes Herbert 6-2, 3-1.
Monfils used an eight-minute injury timeout in the second set to get his back worked on before returning to the court and getting broken in fourth game. He then walked to the net and ended the match.
