The Naomi Osaka comeback tour at the 2025 US Open has ended, as the two-time New York Grand Slam champion and world No. 24 star ceded her Thursday semifinal to No. 9 Amanda Anisimova, who battled back to claim the 6-7(4), 7-6(3), 6-3 victory.
"Naomi is playing amazing tennis," the 23-year-old said of Osaka's US Open run. "She's back where she belongs. I told her I'm so proud of her after having a baby and playing at this level — it's insane."
With her Thursday win, Anisimova is now the only player to ever defeat Osaka in a Grand Slam quarterfinal, semifinal, or final — ending the Japanese fan-favorite's 13-0 run in the later rounds of tennis's major tournaments.
Anisimova's US Open success is even more impressive considering the result of her first-ever Grand Slam final — a brutal 6-0, 6-0 loss at Wimbledon in July.
In a massive turnaround, Anisimova handed No. 2 Iga Świątek, the 2025 Wimbledon champion, a redemptive straight-set loss in Wednesday's US Open quarterfinals en route to reaching this weekend's championship match.
Anisimova's victory means that a US player has now competed in every women's Grand Slam final dating back to the 2024 US Open, extending the country's championship-match streak to five straight Slams.
With even more history on the line, the US rising star now has a second shot at joining No. 6 Madison Keys and No. 3 Coco Gauff in hoisting a 2025 Grand Slam trophy for the US — a feat not accomplished by any single country since Serena Williams won the Australian Open, French Open, and Wimbledon in 2015.
How to watch the 2025 US Open championship match
Just like Keys and Gauff, Anisimova will have to defeat Aryna Sabalenka to claim her own 2025 Grand Slam trophy — with the hard-hitting US finalist holding a 6-3 all-time record against the world No. 1 player, most recently downing the 2024 US Open champion in this year's Wimbledon semifinals.
Anisimova will battle Sabalenka in for the 2025 US Open crown on Saturday, with live coverage of the championship match beginning at 4 PM ET on ESPN.
