Novak Djokovic has been defeated by the local lad John Isner in the quarter final round of the ongoing Western and Southern Open on Friday. Isner won the match in three sets by 7-6(7-5), 3-6, 7-5.

Djokovic had been in good form in this tournament and he was supposed to walk away with an easy win against Isner who is 13 positions behind him in the world rankings. But, the 28 years old American player didn’t let that happen. He played some brilliant tennis and pulled off one of the biggest wins of his career.

This was the 5th match between these two players and Isner defeated Djokovic for the second time.

In the post match interview, Djokovic said, “My performance was extremely poor. It was horrible. I wasted a lot of opportunities and was nowhere close to my best.”

In the opening set, both the players held their entire serves and the set went into the tie breaker.

Djokovic committed quite a few unforced errors in the tie breaker and ended up losing it to get down by a set.

In the second set, Djokovic seemed to be getting into his groove as he broke Isner’s serve in the second game and then, held his serve in the next game to take a lead of 3-0. Thereafter, the Serbian superstar just won his next 3 service games and wrapped up the set.

In the final set, there were no serve breaks in the first 11 games and Isner was ahead by 6-5 when the 11th game ended. The set seemed to be going into the tie breaker, but, it wasn’t to be. With an all important breakthrough in the 12th game, Isner clinched the decider and moved into the final 4.

Isner’s next opponent will be Juan Martin Del Potro of Argentina.
