Six-time winner Serena Williams got off to a winning start at the US Open, powering past 96th-ranked Kristie Ahn 7-5 6-3 as she launched her protracted pursuit of a record-equalling 24th singles grand slam title on day two at Flushing Meadows.
Williams overcame the loss of her first service gamein the opening set to advance at a virtually empty Arthur Ashe Stadium, where artwork by black artists is displayed in honour of the Black Lives Matter movement against racial injustice.
The win was Williams' 102nd at US Opens — a new record that surpassed Chris Evert's previous mark.
"I was really happy with how I just fought for every point no matter how I was playing," said Williams, joking that it felt like she hadn't won a match in straight sets "since the '90s".
It has been more than three years since Williams won her 23rd grand slam title at the 2017 Australian Open — when she was already pregnant with daughter Olympia.
She has come close since, reaching four major finals only to come away empty-handed.
Williams needs one more to equal Margaret Court's record and her chances should be improved by the absence of several top players because of coronavirus concerns or injury.
World No 1 Ash Barty, the second-ranked Simona Halep and Canadian Bianca Andreescu — who stunned Williams in last year's final — are all absent from the behind-closed-doors tournament.
