Jelena Ostapenko was involved in an on-court dispute during her US Open doubles third-round match on Monday, 7 September 2026. The Latvian player urged the umpire to address the behaviour of her opponents' coach.
Ostapenko and her Taiwanese partner Hsieh Su-wei defeated the Australian-Taiwanese pair Maya Joint and Chan Hao-ching 6-4 6-4. The drama reportedly began when Hsieh approached the umpire, and Ostapenko pointed towards the opposing team's coach.
Ostapenko stated that the coach had been clapping and shouting after their mistakes, and sarcastically praising their shots in Chinese. Hsieh translated this for Ostapenko, who described the behaviour as "very disrespectful" and requested a Chinese translator. Ostapenko later told the Daily Mail that she felt the situation was "a little bit too intense from their side."
The fourth seeds concluded their straight-sets victory in an hour and 20 minutes. They are scheduled to play eighth seeds Elise Mertens of Belgium and Russia’s Diana Shnaider in the quarter-finals.
