Jelena Ostapenko and Hsieh Su-wei reach quarter-finals after court dispute

Jelena Ostapenko and her partner Hsieh Su-wei advanced to the quarter-finals of their doubles tournament on Monday after a 6-4, 6-4 victory over Maya Joint and Chan Hao-ching. The match featured an on-court confrontation involving Ostapenko and the opposing team's coach. During a changeover, Ostapenko and Hsieh approached the umpire to allege that the coach was mocking them with sarcastic remarks and clapping after their unforced errors. Ostapenko later characterized the behavior as disrespectful and noted it motivated her to focus on the match outcome. Following the match, Hsieh and Chan did not participate in a traditional handshake. Ostapenko and Hsieh are scheduled to play the eighth-seeded pair of Elise Mertens and Diana Shnaider in the next round. This incident follows a history of on-court disputes for Ostapenko, including a widely noted interaction with Taylor Townsend at the previous US Open.
