Jan. 21 (UPI) -- American Amanda Anisimova dropped her fist set, but roared back to upset Naomi Osaka of Japan in the third round of the 2022 Australian Open on Friday in Melbourne. Ash Barty was among the top seeds to advance.
Anisimova, 20, beat the defending champion 4-6, 6-3, 7-6(5) in a match that took two hours and 15 minutes. The Freehold, N.J., native, who was raised in Aventura, Fla., fired 11 aces and 46 winners in the victory. Osaka totaled five aces, 21 winners and won just 1 of 10 break points.
"Going into this match, I knew I had to play sharp if I wanted to give myself a chance," Anisimova said in her on-court interview.
"She is always going to be playing well. She's an absolute champion. I knew I had to step up my game and be aggressive. I'm so grateful I was able to play so well and get this win."
Anisimova, who also advanced to the Round of 16 in 2019, will face the top-seeded Barty in the fourth round.
"I thought it was a pretty high-level match," Osaka told reporters. "The pace of her ball surprised me, but other than that, it was fun to play."
