U.S. Open

 No. 9 Andrey Rublev reached his sixth Grand Slam quarterfinal by beating No. 7 Cam Norrie 6-4, 6-4, 6-4. Rublev is into his third quarterfinal at Flushing Meadows; he is 0-2 at that stage in New York — and 0-5 at all majors. Rublev next faces 22-time Grand Slam champion Rafael Nadal or 24-year-old American Frances Tiafoe. Other men’s matches on Monday’s schedule: 2014 U.S. Open champion Marin Cilic vs. No. 3 Carlos Alcaraz, and No. 11 Jannik Sinner vs. Ilya Ivashka. Pegula, a 28-year-old who was born in New York and whose parents own the NFL’s Buffalo Bills and NHL’s Buffalo Sabres, reeled off the last three games of Monday’s opening set, which ended with a double-fault by No. 21 Kvitova, and then the last six games after trailing 2-0 in the second. This will be Pegula’s third appearance in a major quarterfinal this season — and third against the woman who led the rankings at the time. She lost to the since-retired Ash Barty at the Australian Open, which Barty ended up winning, then to Swiatek at the French Open, which Swiatek wound up winning for her second championship there. “I just have to play within myself,” Pegula said, “and play smart and be present.” Swiatek arrived in New York having gone just 4-4 since the end of a 37-match winning streak that carried her to six consecutive tournament titles. On Monday, she listened to her usual pre-match playlist — a mix of Pearl Jam, AC/DC, Led Zeppelin and Gorillaz — then came out flat as can be against Neiemer, who is ranked 108th but reached the quarterfinals at Wimbledon in July in just her second major tournament. Niemeier was better in the first set. Far better. Swiatek produced only four winners and 13 unforced errors, got broken twice and never earned a single break point. Then, just winning the second set to pull even was quite the struggle for Swiatek. She got broken early and fell behind 2-1, which is when she draped herself with a towel. She seemed to be talking to herself under there. Whatever went on, Swiatek immediately flipped things around with a three-game run to lead 4-2. Even after getting a chance to serve for that set at 5-3, she double-faulted to close that game. Nothing, it seemed, would come easily on this muggy afternoon, with the temperature above 80 degrees Fahrenheit (26.7 Celsius) and the humidity above 50%. But Swiatek did break right back, helped by a wild forehand from Niemeier, and let out a shout. To a third set they went, and Swiatek completely cleaned up her act: The unforced error count was one for her and 14 for Neiemer. When it ended, Swiatek jumped and threw an uppercut and shook her right fist. ——— More AP coverage of U.S. Open tennis: https://apnews.com/hub/us-open-tennis-championships and https://twitter.com/AP—Sports AP-WF-09-05-22 2129GMT
