Thanks Bob for that clarification.
I wouldn't have thought there was a different interp for a move like this between FED/OBR/NCAA, but it looks like there is.
From what I have researched, OBR prohibits the quick feint feint to 3rd, wheel, step and throw to first. But does allow a feint to 3rd (pitcher then notices R1 starting to 2nd), turn, step and throw to first. Correct? Seems the only difference is that the first move is clearly an intent to deceive R1, whereas the second move is an attempt to retire the runner?!?
How about the original sitch? Should we apply the same rational as the above?
PS. I've never seen a pitcher feint to a base and not come off the rubber either. But I do want to get the call right, if it does happen.
