However, it was 24-year-old Vondrousova who secured the crucial break at 4-4 when a baseline rally ended with Pegula sending a backhand long. The twists and turns kept coming, though, as Pegula began finding her range in the second set. In the decider, momentum looked to be staying with the 29-year-old Pegula as she saved three break points in the first three games and then broke Vondrousova by forcing her long. I just wanted to stay as long as I could and fought until the end and I'm just so happy. For Pegula, it was another quarter-final heartbreak, having never gone beyond the last eight at a Grand Slam.
