Yes, by the rulebook there are two definitions and both have their distinct dos and don'ts. The hybrid falls in neither and is illegal. My point being with the clearly defined set(pivot foot parallel), what advantage does the pitcher have in the hybrid. If his foot is not parallel, then he is in windup. More of a theory/why did FED think this was so important/why can't we use the same rules at all levels discussion. Sent from my SAMSUNG-SM-G891A using Tapatalk
