Federer, who went out of the tournament without dropping his own serve, said that Isner had served superbly on the big points. “He’s got the size, got the power, got the angles,” the 34-year-old said.

“I thought he did very well today when he needed it. The breakers, he served great. Those are the ones he needed. Yeah, that was the difference. It’s tough to get out of the tournament not having lost your serve,” added Federer.
