Until pitchers master perfect force application techniques, catchers only distract.
Catchers whine about pitch locations, pitch movements, dirt pitches and more.
Pitchers focus on proprioceptive, not external messages. Therefore, pitchers require throwing areas on which they practice without catchers. Adult pitcher training areas require seventy by forty feet areas. Adult pitching rubber to home plate back tip distance is sixty feet six inches. Pitching Mound Pitchers require pitching mounds on which they can throw daily with a minimum of maintenance.
