Didn't I see him at the 2005 USO?
Yes you did. I think was the year that he played Andy Roddick in the first round. Him and Roddick were serving ridiculously. Like 140mph bombs it was so intense there for about a half of a set. Then Scoville's forehand was gonzo and game, set, match.
Like stated previously, he has a lot of talent- very aggressive shotmaker. But he has all sorts of consistency issues. It is either hit or miss. However, if he can find the court with his forehand regularly he should be able raise his rankings - then its all about playing the big matches well(think Gonzo- he'll miss by like 10 feet.).
