Serena Williams has earned her 100th victory at Flushing Meadows in style, crushing her quarter-final opponent Wang Qiang 6-1 6-0 in a flawless 44-minute performance.
23-time Grand Slam champion Serena Williams hit 25 winners, compared to zero from 18th-seed Wang and won 90% of her first serve points. The American, who turns 38 later this month, dropped just one game and powered into the last four of the US Open.
China’s Wang Qiang produced one of the shocks of the tournament in the fourth round as she defeated second seed Ashleigh Barty to advance to her first grand slam quarter-final.
The eighth-seeded Williams brought up a century of wins at Flushing Meadows to move to within one of the all-time leader Chris Evert. The Americans share the all-time record for most US Open singles titles.
The six-time US Open champion is seeking a 24th Grand Slam title to tie Margaret Court's longstanding record and is just two match wins away from it.
Serena Williams will face fifth seed Elina Svitolina, who beat Britain's Johanna Konta 6-4, 6-4 to become the first Ukrainian to reach the US Open semi-finals.
