This may sound illogical, but Buxton swings fast. He swings as fast as he runs. It's like his bat is a wand. His arms look too strong. He swings at one speed only (100 mph), same as he runs. What can be done? Well, a fast swing is better than a slow swing to begin with. How to slow that bat down? Stop lifting weights? Meditate on daisies standing quietly in a meadow? Swing a heavier bat? Change his stance? Wait, Bryon (like Mollie did) and then wait again. Go the other way, not as a rule, but as a response to your natural ability to swing fast.
