Lukas Lacko vs Reilly Opelka prediction

I tipped Lacko to win his last qualification match in Wimbledon where he lost to Gojowczyk. He was performing quite well, had beaten Seppi, Brands and Bemelman before tournament. Slovakian likes baseline plays and he has good big serve with strong returns. He has quite solid performance on regular grass surface after disaster Wimbledon tournament. There is no doubt that his experience is much more than young American Opelka. Opelka is my future star player, reminds me Isner a lot. He performs well recently, just having mental problems at some time.Actually, this low bouncing grass tournaments should fit his game style a lot. Kind of same players won the title here in the past years. Moreover, I believe he wants to show his best in homeland country after failed to join Wimbledon. He played 5 tie breaks in last 10 first sets. He also lost to Dancevis in his first match last year here after tie breaks in first set. I expect, first set both players will try to judge opponents. They both can hold serve. I see 7-5 or 7-6 in first set.
