There are some tennis players, such as Frances Tiafoe or Madison Keys or Ben Shelton, who can’t wait for the U.S. Open to come around each year, with its boisterous crowds, its bold-faced names in the stands, its music at changeovers, its buzz. To them, the louder the better. Sometimes, though, it all can get out of control, as happened during a match that ended after midnight. There was a delay of more than five minutes while spectators booed and shouted — egged on by 2021 champion Daniil Medvedev, who was angered by chair umpire Greg Allensworth’s ruling after a photographer interrupted play by going on court.
