The US Open fourth round is set for a captivating all-American showdown as World No. 4 Jessica Pegula takes on rising star Ann Li under the bright lights of Flushing Meadows. Pegula has cruised through her opening matches, brushing aside Mayar Sherif, Anna Blinkova, and Victoria Azarenka without dropping a set.
Ann Li, meanwhile, has been writing her own Cinderella story, moving past Rebecca Šramková before stunning 16th seed Belinda Bencic, and backing it up with a confident win over qualifier Priscilla Hon. While this is familiar territory for Pegula, who is making her tenth career appearance in the second week of a major, Li, is making her first trip to a Grand Slam Round of 16.

Pegula vs. Li Prediction

Li has a comparatively modest 2025 campaign with a 23-20 overall record. While she has reached finals in Cleveland and Singapore, both on hard courts (losing to Sorana Cirstea and Elise Mertens, respectively), Li still lacks title-winning consistency on this surface.
Pegula shows efficiency and composure on serve, with 135 aces and 125 double faults, and a 1st-serve percentage of 61.5%. She also wins 67.6% of points on her first serve and 50.9% on the second. Meanwhile, Li has a promising serving profile, winning 65.3% of her first serve points and 46.8% on her second serve.
However, she converts fewer break points and faces more pressure, saving only about 53% of breakpoints, which may be a key factor when up against a steady returner like Pegula. Taking both players’ current form and metrics into account, Pegula holds a decisive edge owing to superior hard-court results and reliable serving stats.
Prediction: Pegula to win in straight sets
