By the way, since we are talking about pitchers...how about we mention batters!

Batters do not turn their shoulders 90 degrees! Yet they generate a lot of power with their bats.

How do they do that?

Having watched frame be frame video of Mark McGuire hitting a ball, the source of his power was pretty clear. He had a ton of "lag" in his bat and his hands were out in front of his "bat-head".

Is this still the physics thread?

Not to mention McGuire and other great batters exhibit the right arm flying wedge.
