Madison Keys overpowered fellow American Jessica Pegula 6-1, 6-3 in just over an hour Monday to move into the U.S. Open quarterfinals.
Keys, the No. 17 seed and 2017 runner-up at Flushing Meadows, converted on 77% of her first-serve points and used powerful ground strokes to keep rallies short — a little over three strokes on average — to make quick work of her third-seeded opponent and close friend.
Keys said it was tough playing a friend but “at the end of the day we both want to win. We’re all business on the court.”
