Naomi Osaka felt inspired by her U.S. Open run and said she couldn’t be “mad or upset” after losing to Amanda Anisimova in the semifinals on Thursday.

The four-time Grand Slam champion had not progressed to the second week of a major since winning the Australian Open for the second time in 2021.

But she was a set away from reaching another final before Anisimova fought back to claim a 6-7 (4-7), 7-6 (7-3), 6-3 win in a match that finished shortly before 1:00 a.m. in New York.
