World No. 1 Iga Swiatek advanced to her first US Open semifinal on Wednesday with a 6-3, 7-6 (7/4) win over Jessica Pegula of the United States.
The French Open champion will face Aryna Sabalenko for a place in Saturday's final after reaching the last four of a slam for the third time in 2022.
"It's going to be a very tough match. There's going to be some fast serves and some hard hitting, just like tonight," Swiatek said.
There were 13 breaks of serve and a combined 61 unforced errors in Wednesday's error-filled quarterfinal.
"Being in the semifinals for the first time means a lot," Swiatek said.“I am very happy because I worked very hard but I kept my expectations low.
"It was a really close match. I tried to push her back, but she pushed me, so it went to a tiebreak."Swiatek broke the first break of the match in the fifth game and won
The 21-year-old Pole and the eighth-seeded American traded three breaks of serve each in the first eight games in a messy second set.
It was the French Open champion who earned a seventh break at the net to give herself the opportunity to serve for the match.
