Mirra Andreeva reached the US Open quarterfinals for the first time on Monday, September 7. The No. 5 seed overcame Anastasia Potapova 5-7, 6-4, 6-3 in Louis Armstrong Stadium in a match that ended with concern for her opponent.

The comeback required resilience on serve. In the second set, Andreeva saved a break point that would have put Potapova 4-2 ahead. In the deciding set, she fought off two more break points before holding for a 3-1 lead, according to the WTA match report.

The closing moments followed a fall by Potapova on the first point of the final game, while serving at 3-5. The Austrian received treatment on her left knee and returned with it strapped. She played the remaining three points, all won by Andreeva: the match finished with a completed scoreline.
