Coco Gauff has won 6-2 7-6 over Romania’s Elena-Gabriela Ruse to wrap the day session on Ashe. Gauff rallied from 3-5 down in the second set to force a tiebreaker and played cleaner tennis on the big points to avoid the drama of a decider. Gauff, the No 12 seed, advances to a delicious all-American third-round clash against Madison Keys, which appears to be a cinch for Friday’s night session.
