– Suddenly everything seemed perfect for Isner after Davis Cup in MC: he was American #1, he had carried USA to Davis Cup SF winning in clay over Switzerland and France, he had broken into Top-10, and he had proven he could beat top players ( Djokovic @ Indian Wells & Federer @ Davis Cup). But after his disappointing loss vs Juan Monaco in Houston final, everything started going downhill for the 27 year old, as he skipped Monte-Carlo due to fatigue and started the clay season in the blue clay of Madrid, losing in two TB’s vs Marin Cilic. He beated Kohlschreiber in a tough match in Rome ( he was led by a set and a break) but lost to native player Seppi 6-2 6-7 5-7, in a match in which he had many chances to win easily. After that he had a disappointing Nice campaign, losing in QF to Davydenko, who was well past his prime. People started wondering where had gone the clay form which made him beat the likes of Federer, Simon and Tsonga on Davis Cup. As a consequence of his poor clay results he dropped out of Top-10. There were more critics when he disappointed in RG, losing in R2 to French veteran and 261st ranked Paul-Henri Mathieu 18-16 in the fifth. And then, the slump continued in Wimbledon losing to Falla 7-5 in the fifth set after blowing away a 2 sets to 1 lead. Now his favourite part of the season should arrive, with the hardcourts on US soil where he must defend some important points, like US Open QF, Washington SF or his Winstom Salem title. To get his form back he must get back that huge forehand that took down Novak Djokovic at Indian Wells, and recover also that mental fortitude, because since the end of the last season he was winning most of the tight matches, and now he’s losing them.
Good luck John!
