Australian Open champion Stan Wawrinka got into a bit of a tiff with a spectator, telling him to "Shut up," on the way to beating 91st-ranked Thomaz Bellucci of Brazil 6-3, 6-4, 3-6, 7-6 (1) in the second round of the U.S. Open.
In a match that began Wednesday and finished after 12:30 a.m. Thursday, the third-seeded Wawrinka quickly built a two-set lead before faltering a bit, muttering aloud at himself after one miss: "Too many mistakes!"
By the time he was locked in a tight fourth set, Wawrinka was talking directly to a fan who was bothering him, turning toward the Arthur Ashe Stadium stands and saying: "Shut up, man! Seriously, shut up."
Wawrinka was a semifinalist at Flushing Meadows in 2013.
