Jessica Pegula has achieved a career milestone by reaching her first Grand Slam semifinal at the U.S. Open, defeating world No. 1 Iga Swiatek 6-2, 6-4. Pegula, who had never advanced past a major quarterfinal, showcased tactical excellence, reducing Swiatek to 41 unforced errors. This victory marks Pegula's fourth career win over a top-ranked player and highlights her recent form, including a title defense at the Canadian Open. Pegula, the sixth seed and daughter of Buffalo Bills owners, will face Karolina Muchova in the semifinals. At 30, she is the oldest U.S. woman to make her first Slam semifinal in the Open Era.
