Kimberly Birrell vs Jessica Pegula — R128 — French Open

World No. 83 Kimberly Birrell flipped a one-sided opener into an upset of fifth-ranked Jessica Pegula, dropping the first set 6-1 before tightening everything that mattered. The difference was clean tennis: Birrell committed 28 unforced errors to Pegula's 38 and converted 6 of 12 break points to the American's 5 of 12. Pegula's seven aces never offset 57% first serves landed, and Birrell took 61% of second-serve return points. In their first clay meeting, the 1-1 head-to-head tilts the underdog's way.
