I hope John will win, but it will be very difficult, Simon looks very strong, unbelievable in defense and great pusher. Isner has to serve brilliant and achieve lto of easy points. My wish is Isner, but i think Simon in 4.
This will be the same like Delpo- Simon totally different styles with one have the advantage- Simon´s style - it was like to against Delpo- he was frustrated that can´t hit winner againts Simon so he made many errors, because he tried to hit the ball harder and harder. Isner´s serve is better than DElpo´s but in rallies it will be the same, Isner´s movement will be his weakness what Simon can use and also he will be frustrated that with his big FH can´t hit winner and will make many errors. I do believe this match is on Simon´s racquet- or better head. If he will have good strategy and gameplan there is no way he will loose. Only thing where he can´t do much is Isner´s 1 st serve to the lines - 130mhp bombs. But ones he can get ball in rally i like his chances here, he will do the same like against Delpo, will use the difference in movements between them and will get everything back, either Isner will make many stupid UE, or will be to slow with his movements and Simon will by himself hit many winners.
