Why are pitchers always taught to stand with the pivot foot on the middle of the rubber? For sure I don't want to throw any pitches down the middle. Lets say I'm a RH pitcher and move my pivot foot to the right end (looking at the hitter) and my trail foot about the mid point of the rubber. It seems to me that if I have pitches with movement I have a better shot at hitting the inside corner and moving away from the outside corner.
