Pitcher side step

[Atl Blue]

OBR does not allow this

OBR rules don't allow it. OBR umpires do.

It's one more antiquated rule that is not used. A pitcher in the windup position is not trying to fool anyone with a move to first, so a step to the side of the rubber, rather than straight back, is accepted.

As for the set position, I have never seen a step to the side. I have seen pitchers come set in the "open stance", which is legal in OBR.
