re: Why aren't knuckleballers used as reliever?

Lofty tale, mate - were you recruited?

Most mangers don't like them. The ones that will take them are on the edge of their seat waiting to yank you. They need their own catcher a lot of times and to come in with runners on base is more than a manger can stomach with the higher chance for a wild pitch. I had an excellent knuckle ball and above average stuff. People knew I had it in my bag but I wasn't known as knuckle ball pitcher. I wasn't allowed to throw it with runners on base. Knuckleballers are at it generally as a last gasp gimmick to hang on. kKinds like a side arm or submariner. I'm a lefty too and thought with the rarity of it I could carve a future with it, but I never had a coach that would embrace it.
