Coco Gauff is the first American teen since Serena Williams to reach the US Open quarterfinals two years in a row.

So the 19-year-old from Florida knows her way out of trouble on a tennis court.

As the second set slipped away against Caroline Wozniacki in the fourth round, the 19-year-old from Forida needed a chance to think things through.

Gauff turned in the direction of the near-constant chatter coming from Brad Gilbert, one of her two coaches sitting in a front-row seat, and said, “Please stop.”

A couple of minutes later, Gauff said, “Stop talking.”

As the match seemed to be slipping away, Gauff straightened out her strokes and pulled way. 

She collected the last six games for a 6-3, 3-6, 6-1 victory over Wozniacki, the 33-year-old mother-of-two who recently came out of retirement.

“I was getting frustrated. It wasn’t really directed at him. It was just that I needed to reset,” the sixth-seeded Gauff said.

“In that moment, I just didn’t want to hear anything. I just wanted to think about what I was doing.”

Her next opponent will be defending champion Iga Swiatek or Jelena Ostapenko.
