Elena Rybakina beat T. Frodin 6-3, 6-2 at the US Open, converting all three break points she created and saving both she faced. She also won eight of eight service games and outscored Frodin 36-25 on service points.
Rybakina needed just one break in the first set, converting at 2-4, then took the second set by breaking in the opening game and again at 1-4. Frodin never earned a break point in the first set, and only got two chances in the second, neither converted.
The decisive edge came on second serve: Rybakina won 74% of those points to Frodin's 36%. Frodin hit six aces, but five double faults and a 42% first-serve rate kept her on the back foot throughout.
