Darja Vidmanova vs Anhelina Kalinina — R128 — Cincinnati Open

The first serve was the separator, and the gap widened as the match aged. Kalinina won 36 of 51 points behind it to Vidmanova's 32 of 55 — 71 percent against 58 — and in the decider that split ran to 100 percent against 48. The turn came in game 9 of the second set, a break for 5-4, and Kalinina opened the third by breaking again for 1-0. The wild card never earned a break point in that set. Vidmanova matched her ace for ace, six apiece, and took 3 of 5 break points in the opening set before the well ran dry. Kalinina finished it with a break in game 7 for 5-2, 2 hours and 22 minutes in, and the 29-year-old Ukrainian — up from WTA No. 174 to start the season — ends a two-match slide that began with an opening-round exit in Toronto.
