Six-time US Open champion Serena Williams needed just 44 minutes to brush aside first-time Grand Slam quarterfinalist Wang Qiang and win her 100th singles match at Flushing Meadows.
The eighth-seeded Williams won 90% of points behind her first serve, 7/7 net points and 5/5 break points against the 18th-seeded Wang whose winning percentage on first serve was a nightmare 17%. The 27-year-old Chinese won just four points in the second set and in the entire match managed to score just one winner. Hence the result is 6-0 6-1.
Williams, who is chasing a record-equaling 24th Grand Slam title, will play fifth seed Elina Svitolina in the semis, as the Ukrainian progressed past Johanna Konta in straight sets earlier on Tuesday. The pair have met five times in their careers so far, with Williams leading the head-to-head 4-1, but it was Svitolina who won that last meeting, at the 2016 Rio Olympics in straight sets.
