The head-to-head statistics of these players is 0-1, there was an only match last year in Australia, that time Marin Cilic won in five tough sets. Speaking about the Croatian, we can say that his performance is almost equal on different kinds of surfaces, whether it's clay, hard or grass. Recently Cilic hasn't showed the class of tennis he is able to demonstrate, and we definitely can't describe him as a favourite against top-15 players. Though he has gradually began to return to his form, he is still far away from Isner's level. Besides, Cilic hardly won the match against Youzhny last week and then lost to Kohlschreiber. We understand that it's difficult to predict the exact course of this match as John Isner had a little tennis pause, but the probability of Big Man's win is high enough.
Pick: John Isner to win
