Serena Launches Bid for 24th Slam with Straight-Sets US Open Win AFP NEW YORK - Six-time winner Serena Williams got off to a winning start Tuesday at a U.S. Open like no other, being played without spectators and with stringent measures to prevent Covid-19 infections. Williams powered past 96th-ranked Kristie Ahn 7-5, 6-3 as she launched her protracted pursuit of a record-equaling 24th singles Grand Slam title on day two at Flushing Meadows. Elsewhere, Andy Murray fought back from two sets down to win a five-set thriller against Japan's Yoshihito Nishioka, in his first singles Grand Slam match in 18 months because of injury and the coronavirus pandemic. Williams overcame the loss of her first service game in the opening set to advance at a virtually empty Arthur Ashe Stadium, where artwork by black artists is displayed in honor of the Black Lives Matter movement against racial injustice. "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 number one Ashleigh 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. A title win for Williams would also see her become the most decorated women's player at the U.S. Open in the modern era. She is currently tied with Chris Evert for most U.S. Open women's titles with six. .
