I got a chance to see a game in Manchester, NH last night, and Ron Uviedo finished up for the Fisher Cats. You can see why scouts dream on him. His fastball was electric, and his change was devastating (and Binghampton is a very good hitting AA team). He had three strikeouts in two innings. But you could also see why he might run into trouble (as he has repeatedly for the Fisher Cats). He slings his fastball, meaning it can be really hard to have either control or command unless you are a truly extraordinary athlete. I saw no evidence of a useful breaking pitch, except in warmups. There's the conundrum: he was dominating last night, but has pitched pretty badly for Manchester overall. Could his overall approach work in the majors? Probably not would be my guess.
