Jessica Pegula achieved a significant milestone by defeating world number one Iga Swiatek 6-2, 6-4 in the quarter-finals of the U.S. Open, securing her first Grand Slam semi-final appearance. Pegula, the sixth seed, displayed impressive form, breaking Swiatek's serve multiple times despite the Pole's struggles, which included 41 unforced errors. This victory marks a moment of redemption for Pegula, as she had previously lost in six prior Grand Slam quarter-finals. The match was played in front of an enthusiastic home crowd at Arthur Ashe Stadium, where Pegula expressed her gratitude for their support. She will next face unseeded Karolina Muchova in the semi-finals, as American players dominate both the men's and women's draws, a first since 2003. Pegula's recent success includes winning 14 of her last 15 matches, adding to her momentum heading into the next round.
