[In OBR] Touching a base on your last time by that base corrects any baserunning error you made at that base.

Except a "gross miss."

I think we all agree that the runner in the OP is liable to be called out on appeal. The question is, For what? I'm leaning toward "not legally retouching 1B after the catch."

After all, if in the OP everything remained the same except that R1 retreated almost all the way back to 1B but then, without touching 1B, returned to 2B to correct his error, he would be considered to have touched 2B but would not have retouched 1B. Why would retouching 1B prevent him from correcting his error at 2B?

But ASA may contend that there is no legal retouch of 1B until 2B has been retouched on the return. Therefore, in the OP, even though R1 went back and touched 1B, he never legally retouched it.

Incidentally, this is all just surmise on my part. I have no idea whether ASA has thought this situation out to any degree. I can see, though, why OBR observes the principle of "last time by," since it renders all these questions moot.
