NEW YORK (AP) — LOOKAHEAD TO TUESDAY

Both No. 5 seeds are set to headline the first day of the quarterfinal at the U.S. Open. On the men’s side, Casper Ruud of Norway will go up against No. 13 Matteo Berrettini of Italy at Arthur Ashe Stadium. Ruud is the 2022 French Open runner-up and Berrettini was the runner-up at Wimbledon in 2021.

Later in Ashe, Ons Jabeur of Tunisia plays unseeded Ajla Tomljanovic of Australia on the women’s side. Tomljanovic is playing for the second time since she beat Serena Williams and sent her into an apparent retirement. At night, No. 12 Coco Gauff of the U.S. plays No. 17 Caroline Garcia of France and No. 23 Nick Kyrgios of Australia takes on No. 27 Karen Khachanov of Russia. Both night matches are at Arthur Ashe Stadium. Gauff is 4-0 in Ashe this year and is playing the Open quarterfinals for the first time in her career. The 18-year-old Gauff, the French Open runner-up in June, is the youngest American to make it this far at the U.S. Open since Melanie Oudin was 17 in 2009.
