I don't understand why it's so hard for you guys to understand that he has zero command of the fastball. He got cold after the long inning and was missing all over the place again, so he goes to the breaking ball which he has a bit more feel for. He was becoming visibly frustrated with his fastball misses and threw one as slow as 93 in order to get one in for a strike, and still missed. Pearson throwing fastballs all over the place at 93-94 isn't going to help his development.
