Miguel Castro is very thin but I liked what I saw of him this season (Repeating level). Last year struggle with the command, he wasn't fun to watch, I yelled him "throw strikes f***" couple of times, it was impossible to him throw strikes and when things got tough he tended to overthrow.
This year he look calm on the mount, throws strikes, miss bats with fastball and secondary stuff but he's repeating level.
Tirado : Sleeper, like him a lot
Labourt : If he can throw strikes he'll be somebody. Labourt haven't good stuff but he's lefty, you always get it something good of lefties who can throw strikes.
