Isner is all about serve to be fair, nothing new but that only thing which can be said about big American. He is after knee injuries so still not in best shape, but as long as his serve is fine, he wins. Haas confirm his good form against lower class players, he beat Johnson without much fuss, but had to save a few break points, so he is not invincible here. 3 out of 4 meetings were extremely close 3 setters. I think that both will be focused on own serve as it will be most crucial here taking into account how well Isner serves and that it will be hard to break back for Haas.
