Core Event
On Saturday night at Louis Armstrong Stadium, No. 13 seed Naomi Osaka defeated 23rd-seed Elise Mertens 6-3, 3-6, 7-5 to reach the fourth round of the 2026 US Open. Osaka called a medical timeout in the third set for a persistent left-Achilles issue, then rallied to win ten straight points and close the match with a match point at 6-5. The win sets up a meeting with second-seed Elena Rybakina.
Background & Context
Osaka entered as a two-time US Open champion (2018, 2020) and recent Wimbledon semifinalist. Since returning to the tour in 2022, she has a 28-10 record this season and has reached the second week of three Grand Slams in 2026. Her on-court fashion—ranging from an Allen Iverson-inspired look in round 1 to a custom Thom Browne ensemble in round 2—has drawn media attention.

Osaka also urged spectators to respect tennis etiquette and keep noise to a minimum, referencing a disruptive first-round incident involving social-media influencers.
Conflicting Reports & Gaps
- Injury severity: Osaka’s own comments label the condition both “nagging” and “not a big injury,” reflecting differing characterizations.
