Amanda Anisimova came to play this time.

No. 8 Anisimova, after getting completely run over the last time she took on Iga Swiatek at the Wimbledon finals earlier this summer, more than held her own on Wednesday afternoon at Arthur Ashe Stadium. The American picked up the 6-4, 6-3 win in straight sets to make it into the semifinals of the US Open.

Anisimova, who entered the tournament as the No. 8 seed, will now take on either No. 11 Karolína Muchová or No. 23 Naomi Osaka in the semifinals on Thursday. Osaka rolled over Coco Gauff in straight sets in her fourth-round match on Monday to reach the quarterfinals. Jessica Pegula is the other American still standing on the women's side of the tournament. She'll take on top-ranked Aryna Sabalenka in her semifinals match.

Swiatek absolutely dominated Anisimova at the Wimbledon final in June. She picked up a wild 6-0, 6-0 win in straight sets to pick up what was her sixth major championship and first ever Wimbledon title. She did that all in less than an hour, too, and is now the first Polish woman to win Wimbledon in the tournament’s history.

But whatever went wrong for Anisimova in that match didn’t carry over at all. Anisimova kept pace with Swiatek in the first set before finally jumping ahead to the early win. She quickly forced several errors in the final game, too, and had Swiatek on her heels the entire way.

Swiatek found her footing briefly at the start of the second set, and jumped up 2-0 after scoring eight of the first nine points. But Anisimova rallied right away again and tied the match up, and then she pulled up 3-2 after an incredible rally to stun Swiatek for the point.

From there, Swiatek simply looked done out on the court. She made seven unforced errors in the second set alone as Anisimova cruised to the finish to grab her upset and secure her trip to the semifinals.

Anisimova entered the tournament ranked No. 9 in the world. This is already her best run at the US Open, and she’ll now make it into just her third semifinals at a grand slam in her career. Swiatek, on the other hand, will now miss out on the semifinals round of a grand slam for the first time this season. She made it to the semifinals of both the Australian Open and the French Open before her Wimbledon win.
