Emma Navarro vs Anhelina Kalinina — R64 — Cincinnati Open

She broke Anhelina Kalinina in the opening game of the second set, handed the break back in game 6 for 3-3, then took it again in game 9 for 5-4, her first-serve points won climbing to 79 percent; seven of her 14 aces landed in the closing set.
