Andreeva overcomes Potapova at the US Open: A victory of adaptability

Mirra Andreeva reached the US Open quarter-finals for the first time after fighting back to beat Anastasia Potapova 5-7, 6-4, 6-3 in the fourth round on September 7, 2026. The 19-year-old fifth seed struggled early, making double faults and unforced errors as Potapova took the opening set 7-5 with far greater consistency. Andreeva adjusted in the second set by shortening rallies and stepping inside the baseline, forcing Potapova into mistakes and levelling the match at one set apiece. The decider was tight until Potapova appeared to hurt her leg while chasing a ball near the baseline. She bravely finished the match, but Andreeva sealed the win with a backhand winner and then helped her opponent off the court. Afterward, Andreeva called Potapova a good friend and said it was not the way anyone wants to finish a match. The victory extends Andreeva's deepest run at the US Open and sets up a quarter-final against the winner of Iva Jovic and Coco Gauff. The match showed Andreeva's ability to adapt under pressure, but it also left questions about how she will cope against a fully fit opponent of higher ranking.
