Hanne Vandewinkel vs Karolina Pliskova — R128 — US Open

Down 2-5 in the second set with 17 unforced errors already spent in a lost opener, Pliskova broke back in game 8 for 3-5 and again in game 10 for 5-5, then hit 13 winners against seven unforced errors in the decider, a set after leaking 19. The error column decided this, not the serve. Vandewinkel had the better of the break-point ledger, 6 of 11 to Pliskova's 6 of 16, and matched her point for point at 110 apiece, but the 22-year-old Belgian held just 8 of her 14 service games. The 34-year-old Czech, whose last two matches had yielded two games apiece, saved one match point to Vandewinkel's three across 2 hours 24 minutes, and gets No. 16 Diana Shnaider next.
