I'm always confused when people say a pitcher is fine if his arm is strong. A players legs, hips, and torso are very important parts of the pitching equation, even for a pitcher like Fiers who relies more on control. The largest muscles in your body aren't in your arm and it is quite easy for a pitcher to be fatigued enough to throw off his control without his arm being impacted at all. Even with his YTD numbers he is a decent SP. I'm most excited about him because he's performed at EVERY level, while many of the current crop of young SP may have already put up their 'career' month.
