Re: Ismael Guillon - more than a sleeper
I saw him last night and the difference to me was locating a changeup/curve/whatever-it-is-that-wasn't-a-fastball. He was pretty consistently throwing it in there for a strike and getting ahead of the batters. No wild pitches either, although he didn't have many batters get on base.
I hope he can repeat last night, but we'll see.
