Frances Tiafoe threw up during his first-round match at the Australian Open on Monday along the way to a five-set victory and said afterward he might have quit if this had been just a run-of-the-mill tournament. The 17th-seeded Tiafoe, who turns 27 in a week, managed to win the topsy-turvy match against Arthur Rinderknech of France 7-6 (2), 6-3, 4-6, 6-7 (4), 6-3 in 4 hours, 8 minutes. “If it was any other, probably, event, I probably would have let it go,” Tiafoe said about getting sick late in the fourth set.
