The US Open women's singles tournament is officially down to two players: the world No. 2 and an American in her first career Grand Slam final.
No. 6 Jessica Pegula defeated Karolina Muchova 1-6, 6-4, 6-2 on Thursday to advance to her first major final at age 30. While she has won six WTA events, she had previously never advanced past the quarterfinal of a Grand Slam.
The final is scheduled for Saturday at Arthur Ashe Stadium.
