Runner on third. The pitcher assumes the windup position. He steps backwards off the pitcher's plate with his non-pivot foot first and proceeds to assume the set position. I was told by a fellow umpire that "in high school, as long as the pitcher does not feint/make a move toward a base (attempt a pickoff) that he can step off the rubber with either foot. But, if he is trying to pickoff a runner - he must step back with his pivot foot.

Which is correct? And can anyone site a rule in the NFHS 2002 rule book?

Thanks!

Per FED 6-1-2 .... With his feet in the wind-up position, the pitcher may only deliver a pitch or step backward off the pitcher's plate with his pivot foot first....

In order to change positions the pitcher has to step off with his pivot foot.

Thanks for your help!
