Naomi Osaka surged back to the semifinals of the U.S. Open on Wednesday with a straight-sets defeat of Czech 11th seed Karolina Muchova.

The Japanese 23rd seed, enjoying her deepest run in a Grand Slam since winning the Australian Open in 2021, held her nerve to defeat Muchova 6-4, 7-6 (3) in just under two hours.

The two-time U.S. Open champion Osaka will now face eighth seed Amanda Anisimova in Thursday's semifinals, and will head into that showdown brimming with confidence after another polished performance.
