Since jbooth and a few others have asked about turning the barrel, I'm starting a new thread to help answer the question. Turning the barrel is (simply put) getting the bat from vertical to flat so the rear leg/hip drive the barrel to contact. The pressure sensation must be in the hands. However, that doesn't mean the phalanges are causing it. The direction of the barrel turn is key. It is NOT in a line with the catcher. The barrel is turned in between the backstop and the dugout behind the hitter.
Bio-mechanically, turning the barrel is applying force perpendicular to the handle. The rear humerus adducts while the lead humerus both internally rotates and abducts. The teres minor is partially responsible for the rear arm's adduction, though it's rather weak. The latissimus dorsi serves to adduct the rear arm as well, as does the teres major.
This clip of Adrian Gonzalez displays the action rather well.
