Sure, the first time out it actually was his big league debut, he was visibly nervous and rattled, didn't have any idea what to do besides throwing as hard as he could (97-99) when he started to get hit around and couldn't locate his secondary pitches, either. He definitely made some progress in the the minors this past summer.
Between the Tigers and the Royals and Indians...the pitching it going to continue to improve in the division, unless CLE trades Bieber/Plesac and does another rebuild. Betting money is they give it one more final go with Bieber and Ramirez next season.
