Isner is flat out trash. He's not a tennis player, he's a server. That's it. Backward hat makes him look like a fucking idiot as well.
Learn to return a serve and make a shot dipshit, that was awful. Unforced errors, haven't even looked but the guy has no skill in shot making and while we pretty much knew that, what a cash grab this guy has made without actually being able to play tennis.
