Keys edges past Korneeva 7-5 6-4 in US Open first round

Madison Keys came through a tight straight-setter in the US Open first round, taking out Alina Korneeva 7-5 6-4 without ever pulling clear. The margin came off the second ball: Keys won 48.5% of her second-serve points while Korneeva managed just 37.9%, and that gap decided the long service games at the end of each set. The American's first-serve numbers were modest too, 57.1% in and 59.1% won, and five double faults kept the door ajar, though four aces gave her free points Korneeva, who served none, never had. It was a workmanlike start to her campaign in New York.
