Reds/Phils game tonight. Sac bunt. F3 fields it and runs towards BR. BR backs up (ie back towards home plate) and F3 somehow forgets to tag him. BR goes to first and is safe.

A few people have said he should have been out because "you're not allowed to back up between home and first."

I've never heard that and couldn't find it in reading OBR.

Anyone?
