Oliynykova beat Brantmeier 6-4, 6-4 at the US Open, taking both sets with a break in the final game. She put 69% of first serves in and, crucially, saved 7 of 11 break points, while Brantmeier saved only 2 of 7 on her own serve.
Both sets followed a similar path. Oliynykova dropped serve in the opening game (0-1) each time, but broke straight back at 1-1 and kept pressuring. In the first set she moved ahead with a break at 4-2; after Brantmeier pulled back to 5-4, Oliynykova broke again to close it out. In the second, Brantmeier twice led, at 0-1 and 3-4, but Oliynykova answered with a break at 4-4 and then sealed the match with another at 6-4.
The scoreline was tighter than the key numbers suggest: Brantmeier actually won more return points (32-29) and hit the only ace, but Oliynykova's five breaks to four proved decisive. Her 69% first-serve accuracy contrasted with Brantmeier's 42%, and the 63% to 28% gap in break points saved was the standout difference.
