"I don't believe that the average fellow has anything like a true line on the value of wrist action in hitting anything—a baseball, a golf ball, a tennis ball or a polo ball. If you watch most of them, you will see they are trying to hit with their bodies, with their shoulders, with their arms—with almost everything except their wrists. I think it comes because most of them are overanxious, all tied up, too tense. They start by gripping too tightly. That kills off the hands and wrists. Their wrists get locked and then they have to swing their shoulders and bodies in. You'd be surprised how far a fellow can hit a ball, using only his wrists. I know I've been caught off guard or out of position on a sharp breaking curve, have had to slap at the ball, using only my wrists and have now and then watched it sail over the fence. The wrist is the mainspring—both wrists in baseball and golf. If you get them to work the rest is fairly easy. If you don't get them to work you are not going to do any good hitting. You can't get any speed in closing a door if the hinges are rusty and won't work. Hack Wilson must have great wrist action, for no short, stocky guy is going to hit that many home runs without a lot of it."
