I don’t need a crystal ball to see trouble ahead.
Elbow above the shoulder equals strain on shoulder, arm, elbow and a likely trip to the DL, and if you happen to be an over-the-top thrower the problem is greatly exacerbated. You need to take a good long look at your arm slot, for openers, and see if this is the case; if so, a change in said angle would be in order—come down to a 3/4 arm slot, which would take a good deal of the pressure off. Also, if you’re not doing so, you need to really get your whole body involved—legs, hips, torso et al., to get more power into your pitches so that the shoulder and arm would just go along for the ride. Ideally the elbow should be on a level with the shoulder (I speak from experience, being one of those exasperating sidearmers). And don’t overthrow. 8)
