Galovic V. vs Sinner J. prediction

in second round of us open qualies croatian galovic will face with italian youngster sinner. in my oppinion galovic is here underrated and this coeff. is just to big. he is not lot bad player and he will have chances in this match. he beat very easy smith in previous round so he certanly has quality to beat sinner. on other side sinner is good but he know to lose against lower ranked players, for me this is big value bet
