The FB isn't used enough in high school. Over the past few years, I've seen the breaking ball take over the game. Location is KEY. Teach the pitcher to throw his FB at different speeds/location. Hey, throw a BP FB in every once in a while.
I agree with Coach May, why throw anything else if you can control the hitter with FB's?
In calling pitches it depends upon what batter you're facing and what type of pitcher is on the bump.
Do not get into a pattern...pitch backwards every once in a while. This game is all about making adjustments...
This is a GREAT GAME!
