coach2709 posted:My pitching coach swears up and down 12 years ago he did this when he was head coach and I don't think in 20 years of coaching HS baseball this was ever allowed. This is a college rule if I'm remembering correctly.
It wasn't allowed for the 20+ years I umpired HS ball.
FLA, iirc, has (or had) a rule that allows this (but it's not quite the NCAA rule).
