If these slow pitchers are so effective at throwing off hitters, why don't coaches look for them during tryouts?
Obsession with speed. On our team we gave a gunner who the coach names as the number one pitcher, but stat wise she is 3rd in k's. 3rd in fps. And 2nd in walks. But he likes her because she is fast.
To answer the original question, I've seen some success with a true gunner followed by a good junk baller. With the junk baller throwing slower but locating very well
