LONDON — Zheng Qinwen became the second top-five 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.

Zheng Qinwen made her maiden grass semifinal last week and that wasn't the only good thing about her Queen's run as the Chinese tennis star is now also a top-4 player for the first time in her career.
