Matteo Berrettini and Casper Ruud are in action in the first men's quarterfinal at Flushing Meadows.
Both men have been the runner-up at another Grand Slam tournament: No. 5 seed Ruud at the French Open this year, and No. 13 seed Berrettini at Wimbledon last year.
It is raining, so they are playing under a closed roof at Arthur Ashe Stadium. With showers in the forecast all day, the U.S. Open called off all junior matches that were scheduled for Tuesday.
The Berrettini-Ruud winner will face Nick Kyrgios or Karen Khachanov in the semifinals. Kyrgios vs. Khachanov will be the last singles match on Tuesday, following 18-year-old American Coco Gauff against Caroline Garcia in the night session.
The other women's quarterfinal Tuesday is No. 5 Ons Jabeur against Ajla Tomljanovic, the player who eliminated Serena Williams in the third round.
