Letter of Certification
(The only one Ted Williams ever gave out for hitting knowledge and instruction)

From the World's Greatest Hitter...
"Mike Epstein played for me for three years when I managed the Washington Senators. He was always a keen student of hitting. I see Mike frequently and have parried batting technique and theory with him — both the physical and mental sides — on many of those occasions. I'm a tough guy to please and impress, but I believe Mike comprehends and teaches the science of proper hitting as skillfully as anyone I have run across in all my years in baseball."
                       —Ted Williams

     

Ted Williams wrote that the ultimate contact point is made when the barrel of the bat and ball meet at a 90 degree angle.

This is the " Ideal Impact Zone". This is what the ImpactBat Reinforces.
