Serena Williams underlined her tag as the favourite for the US Open with a brutal quarter-final win over China’s Wang Qiang in just 44 minutes.
The 37-year-old American broke serve five times and hit 25 winners as she eased to a 6-1 6-0 win over the 18th seed on Arthur Ashe Stadium
Williams, seeded eighth, is chasing a record-equalling 24th Grand Slam title.
She will face Ukraine’s fifth seed Elina Svitolina, who beat Britain’s Johanna Konta, in the semi-finals.
“When I play someone who is playing well I have to step up or go home and I’m not ready to go,” said Williams, who earned her 100th singles win at the US Open.
The six-time US Open champion has not won a Grand Slam title since returning from giving birth to daughter Olympia in September 2017.
