Iga Swiatek’s U.S. Open title defense ended with a 3-6, 6-3, 6-1 loss to Jelena Ostapenko in the fourth round on Sunday night.
The loss also means Swiatek's stay at No. 1 in the WTA rankings will end next week, when current No. 2 Aryna Sabalenka will rise to the top spot for the first time.
Swiatek's shots were off-target in Arthur Ashe Stadium and she had a difficult time handling the hard hitting from the 20th-seeded Ostapenko, who won the 2017 French Open.
This was not necessarily a huge surprise, based on their previous matchups: Ostapenko has now improved to 4-0 against Swiatek over their careers. No other player owns four victories against the woman who has led the WTA rankings since April 2022.
Ostapenko's first quarterfinal at Flushing Meadows will come against Coco Gauff, the 19-year-old American who eliminated Caroline Wozniacki 6-3, 3-6, 6-1 earlier Sunday.
