No. 5 seed Zheng Qinwen loses Wimbledon first round again

LONDON (AP)—Zheng Qinwen became the second Top 5 seed to lose in the first round at Wimbledon on Tuesday when the Olympic gold medalist fell to Katerina Siniakova, 7-5, 4-6, 6-1.

The 22-year-old Chinese player was the No. 5 seed at the All England Club and her loss came hours after third-seeded Jessica Pegula was upset by Elisabetta Cocciaretto.

It was Zheng's third straight first-round exit at Wimbledon.

Siniakova is a three-time doubles champion at the All England Club, including winning last year alongside Taylor Townsend. Siniakova has won 10 major doubles titles—seven with Barbora Krejcikova, two with Townsend, and one with Coco Gauff at last year's French Open. Krejcikova got her Wimbledon singles title defense off to a winning start Tuesday.

Siniakova will face four-time Grand Slam champion Naomi Osaka in the second round.
