What I am seeing with Roark is he is reverting back to his minor league days---he would pitch well once in a while but get bombed on other days.
What is his real strength? Sitting in the stands I could not see pitch location. But I was charting his speeds. On his fastball anyway (offspeed, that's another story). 91, 92, ..... occasionally 93 but not often. Now, I read that he said that his problem last year was "overthrowing": he'd come in a game knowing he needed to go only an inning or two (as a reliever) so he could throw as hard as he wanted, and he was throwing 95, 96, maybe higher. But he couldn't locate his pitches at those higher speeds, so he was going to dial it back down, which he apparently has. But is he locating his pitches any better? Apparently not.
