Why do HS coaches call pitches?
Coaches calling pitches are doing nothing to help their pitchers and catchers become a "Battery". They are creating "lazy" thinkers of the pitching game. Unless of course we are talking about the perennial nationally ranked high school teams' coaches! There are exceptions to this opinion.
Besides, the coach that never called pitches ever in his baseball career is not really experienced at the calling game. The pitcher and catcher should call their own game. yes, I am here to tell you that coaches need to allow their catchers and pitchers to call their own game. This is how they learn the game, their opponents, their own abilities, etc... They have a better feel for the "holes" of each hitter in the batters box. They have a better memory of each hitters history, they see the flaws in the stance, the movement of the hitter's hands, the plate approach, etc... It also creates a comfort zone for most pitchers to beleive in their pitch. Also, it creates ownership of the outcome of the game. Well maybe not, just an opinion.
Setting up a hitter is a very individual thing for the pitcher and catcher because first of all the pitcher needs to believe in the pitch he is going to go at the hitter with depending on the count. Most of the time coaches over coach anyway.
example: We have a good fastball pitcher on the hill and the 3 hitter at 0-2. Coach calls for a change down and away, ok...but the pitcher better keep it down and out of the hitters wheel house or out of the strike zone which most often becomes ball 1 then another off speed for ball 2 and then another for full count...what is happening to the pitch count? What good was it to get ahead in the first place? Why speed up the hitter's bat when the hitter could not put his bat on the heater? Why not step up the heater by climbing the ladder?
Why even show the off speed stuff in the early innings??? Especially if you don't need it until later in the game after you have seen the lineup come through?
Coaches should not call pitches unless of course they have called many games before in their baseball past or learned from a coach then spent time teaching how to call a game. But coaches should allow their pitchers and catchers to call their own game so they learn how to set up hitters among other reasons....
