Re: Will John Isner ever win anything big?
Isner reached a career high last year, imo. I don't see him cracking the top 10 again .Slams are out of the question for obvious reasons. I think he could get lucky and win a masters1000 if he gets a little bit of luck, and plays well. Even that is unlikely though.
That said, Isner has potential to make any match exciting with his serve, as we've seen before.
