Top-ranked Swiatek advances with 3-set victory in San Diego

SAN DIEGO (AP) — Top-ranked Iga Swiatek needed more than two hours to post a 6-4, 4-6, 6-1 victory over Zheng Qinwen of China in her opening match Thursday at the WTA 500 San Diego Open. Contending with a steady mist that caused a 30-minute delay just after the match’s initial point was played and a brief halt early in the second set, Swiatek shook off the hard-hitting Qinwen, ranked 28th, in the Round-of-16 match. Swiatek’s victory was the 61st on the WTA tour this year for the 21-year-old from Poland, who has held the world’s top ranking since April 4.
