I’ll say it. The serving display John Isner just put on against Juan Martin Del Potro was not fair.

He completely took the racquet out of Del Potro’s hand. It was an absolute clinic out there. Isner served up 13 aces in his 6-1, 7-6(2) semi-final victory, which on paper, isn’t overwhelming, but there were so many unreturned bombs that Del Potro didn’t have an inkling of a chance to break. Keep in mind Del Potro stands at 6’6’’ with a 7’5’’ wingspan and he STILL couldn’t figure out Isner’s serve.

Isner also blasted a 117mph forehand winner, which seemed closer to the 200mph range. He came out swinging for the fences on the serve and forehand side, which ultimately paid off.

With that being said, I give a ton of credit to Del Potro for an incredible 15-match streak and Isner undoubtedly benefited from him being gassed.

Hats off to Isner for digging out of his 2018 slump with his first run to a Miami Open final.
