Thank you, CPLZ, for your thoughts. Is it possible that a one-handed follow through could put additional strain on the labrum? Would a two handed follow-through share the load of the swing, particularly with a hard swing that misses the ball (thus without the impact of the ball to slow the swing)? Incidentally, the only time son had pain prior to surgery was during the swing, so I am thinking that some act of the swing must put strain on the labrum.
