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 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.

"I wasn`t expecting to have this kind of good experience so soon in my career," said Swiatek, who has notched six titles in 2022, including the U.S. Open, French Open and Indian Wells. "It`s like my dreams are coming true." Playing on a slick hard-court surface, both players made frequent use of drop shots, which caused Swiatek to take a fall in the second set as she attempted to return a successful Qinwen drop shot. The first and second sets were tied at 4-all. In the opening set, Swiatek broke Qinwen`s serve for a 5-4 lead before holding serve. With the score tied 4-all in the second set, it was Qinwen who broke Swiatek for a 5-4 advantage. Qinwen fended off five break points before claiming the ninth game.
