Hitters practice too and a good hitter can hit any pitch (particularly if they know its coming). Hitting is about timing and pitching is about disrupting timing. Unless you IBB every hitter, whatever you throw runs the risk of getting hit. If you remove the FB from the pitcher's arsenal, you've left the batter with one less speed to have to adjust to (and reduce the top end speed range by several mph to boot). Why is a change up effective? Because of the speed differential. When is a change up effective? When the hitter is expecting a faster pitch i.e., the change disrupts the hitter's timing. What if the pitcher's best pitch is a curveball - should she throw it every pitch? How often should she throw it during each at bat or the 2nd, 10th, or 25th time she faces the same batter? What pitch has the pitcher thrown the most of and has the best control of? Its a rare exception if its not the fastball. You mix your pitches, you change your patterns, sometimes you save your best pitch for when you need an out the most. Can you pitch off your fastball? Yes, if its above average, well located, and set up by your other pitches. Can most pitch off their fastball? Probably not, but that's no reason not to abandon it. Ever seen a #4 hitter take 3 change ups in a row looking for a K? Ever seen an All-Star MLBer take a FB down the middle for a called 3rd? Were these pitches unhittable? No, but somewhere earlier in that at bat, or a prior at bat, or prior game, good pitch calling and proper execution set up these outcomes.
