Somebody asked me about calling pitches and my thoughts on if the coach should call or the catcher? My thoughts are this, the catcher has the best view in the house she see's everything from where the batter is set up in the box to how they are swinging hand position and grip etc etc. The pitcher of course has the power to veto because ultimately she has to throw the pitch and she knows what the ball feels like that day are the seams too high or too low does the ball feel heavy is the mound tore up is it soft or too hard and what pitches are working that day, all the variables that matter to a pitcher. That is why it is very important for the pitcher and catcher to practice together often and on different surfaces so that the catcher knows the pitchers adjustments.
In my case I like to call the pitches at least one time through the order not because I know everything but mostly because pitch calling is about setting batters up and these young catchers are still very new to that. I've come to recognize various swings because I pitch so often in my games and to various kids weekly and have come to recognize certain tendencies from certain swings. However, I like my catchers to pay attention to how I set batters up and why and to always be at least 2 pitches ahead, don't just throw a pitch because its seems like a good idea. Be mindful of the batters height, body tilt, hand position, grip, swing path, don't fall victim to the 2 strike phobia. The goal is to teach these young catchers the art of setting up batters and let them have at it because like I said they have the best seat in the house....
