During a changeover 26 minutes into his second-round match against Sebastian Ofner, Frances Tiafoe reached into his bag, pulled out a fresh top and changed his shirt. Twenty-four minutes later, up by 4-1 in the second set, he swapped that shirt for a clean one again.
Between the second and third set, Ofner took a medical timeout. Tiafoe had been wearing his shirt for only about six minutes, but he was ready for another.
Before the match ended, Tiafoe changed his teal sleeveless shirt once more. By the end of his straight-sets victory over Ofner, there was a pile of sweaty shirts by Tiafoe’s bench.
