MIAMI (AFP) – John Isner produced a blistering Miami Open semifinal display against crowd favorite Juan Martin del Potro to win 6-1, 7-6 (7/2) and snap the former US Open champion’s 15-match winning streak.
It was a phenomenal effort from the American who blasted down 13 aces and took just one hour and 23 minutes to floor Argentina’s Del Potro and book his place in Sunday’s final.
Isner will meet either Alexander Zverev or Pablo Carreno Busta, who play their last four match later Friday.
Isner, 32, arrived in South Florida with just six wins to his name in 2018 but has improved with every match in Key Biscayne and is now eyeing his first ATP Masters title.
“I have played a lot of big matches and not been able to get such a good start but I am playing some of the best tennis I have played in such a long time,” Isner said.
“I am so happy. He is so tired and has played so many games and although the first set was quick I knew it wouldn’t be like that in the second.”
“I didn’t think I could turn it around like this after the year I have had so far. I started the tournament well and I have improved with every game.”
