NEW YORK — Serena Williams began her latest attempt to win a 24th Grand Slam singles trophy by beating Kristie Ahn in the first round at the US Open on Tuesday. Things didn’t go as smoothly for her sister as Venus Williams lost in the first round of the event for the first time in 22 attempts.
In her match, Serena Williams split the first 10 games before pulling away to win 7-5, 6-3. The victory was her 102nd at the tournament, breaking the tie she held with Chris Evert for the most by a woman in the Open era.
Williams hit 13 aces and lost only six points on her first serve.
“It’s been years, since the ’90s, since I won a match in straight sets,” Williams said. “It felt really good, I was like, ‘Serena just be Serena and close it out,’ and I know I can do that so it felt really good.”
Williams, who turns 39 this month, has won the tournament six times and has been runner-up each of the past two years. She’s seeded No. 3 and hoping to tie Margaret Court’s record of 24 Grand Slam singles titles.
“I was really happy with how I just fought for every point, no matter how I was playing,” Williams said. “I was like ‘OK Serena, just gotta get my Serena Focus back,’ so that’s what I’ve been trying to work on today.”
Venus Williams was beaten by No. 20-seeded Karolina Muchova 6-3, 7-5.
It was small consolation to Williams that by appearing in the tournament for the 22nd time, she broke the women’s record in the Open era. She had been tied with Martina Navratilova.
Williams’ sister, Serena, was among the few spectators for the match, having already won on Tuesday.
The 40-year-old Venus was the oldest player in the draw. She fell to 1-7 this year.
Earlier, Garbine Muguruza opened the second day of the tournament by dedicating her win to a former top-10 player who had just revealed her cancer diagnosis.
Muguruza, the No. 10 seed, defeated Nao Hibino 6-4, 6-4 and thought about Carla Suárez Navarro, who shared her diagnosis publicly earlier in the day.
Suárez Navarro revealed in a tweeted video that she’ll need six months of chemotherapy to treat Hodgkin lymphoma.
“I was expecting to see her in this tournament,” Muguruza said. “You know, she’s such a nice woman, so sweet, so kind, so humble.
“I, for sure, will dedicate this win to her because I want her to feel that we are behind her, that I am behind her, and I will go and see her at some point when it’s fine.”
Navarro, who turns 32 on Thursday, was ranked as high as No. 6 and has reached Grand Slam quarterfinals seven times, including at Flushing Meadows in 2013 and 2018.
Others advancing included reigning Australian Open champion Sofia Kenin, No. 9 seed Johanna Konta and No. 16 Elise Mertens.
