His Second start was a product of facing an AL lineup for the first time. Remember...his first start was against the NL lineup of the Brewers, a lot of small ball hitters and no DH. He should bounce back his next start and blow everyone away, but he just needed to get use to Pitching against an merican Leauge Team.
If you watched the game you would of noticed he loaded up the bases in the first inning and ended up striking everyone out without allowing anyone to reach home plate, so he's good in high pressure situations.
Just don't give up on him yet...it will pay off
