[O.B.Left]

Its all about the right elbow's position, to my mind. That is why Homer used it, the right elbow, to define the various strokes. PItch , Punch, Push etc. The elbows position promotes the corresponding hand, wrist alignments. Pitch elbow begets a early left wrist cocking via the bent right elbow and a delayed release for instance.

By the way, since you are an old hitter type, Pitch ish elbow does not mean that you cant use a right arm throw.
