Two-time U.S. Open champion Venus Williams was ousted in the fourth round by 24-year-old Karolina Pliskova, who won a dramatic third-set tiebreaker.

Pliskova dropped the first set 4-6, but evened the match by winning the second set 6-4 (despite going down a break). Williams earned a match point in the third set up 6-5, but Pliskova saved her tournament and forced a tiebreak. On her fifth match point, up 6-3, Pliskova hit a safe serve to the 34-year-old Williams, but the return sailed long to end the match.
