From Eric Longenhagen ESPN Josh Hader, LHP, Brewers -- It's not your typical starter's delivery but Hader's stuff, and the way he uses it, make him a viable rotation option in my eyes. His fastball sits in the mid to upper 90s and is absolutely unhittable if he locates it. The slider is regularly a 50 or 55 and plays up against lefties because of Hader's unique arm slot and action. He's shown the ability to throw it for strikes and locate it toward the back foot of right-handed hitters. The changeup is behind but Hader at least maintains his fastball arm speed when he throws it, which will keep hitters off balance enough to generate weak contact if not swings and misses. If Hader can maintain his stuff deep into games, improve his changeup and locate his fastball to his glove side more consistently, he's a top-of-the-rotation starter. The more likely outcome is that his rate stats are indicative of a No. 2 starter, while stamina and inefficiency limit his innings and therefore his value to something resembling a No. 3.
