I’ve heard rumors out there that a split finger fastball is very hard on the elbow, since it strains the tendon that run from your hand, through your elbow, and into your shoulder. By splitting your index and forefingers, you put a strain on that tendon. Is this true, is there a good possibility of elbow injury in throwing a “splitter”?
For me personally, the splitter seems like the perfect pitch. I have a good, hard moving fastball with a natural sink with excellent control. I think that natural sink has made it difficult to master the slider and curveball, and I’ve struggled in finding an effective “out” pitch. I also seem to struggle with arm speed consistency in my secondary pitches (including a circle change). With a splitter, I don’t expect to to experience the same arm speed inconsistences and my natural sink should work well with the splitter. However, I am hesitant to incorporate the pitch if there’s a good chance of elbow injury.
