Always more than one way to skin a cat. I have found that it also screws with the defensive players and they will hesitate that half second it takes for the runner to be safe. It can get strange. More than once we had the catcher chase our runner back to third, then take off after our runner going back to second, and then watch as our runner went back to first. All the while this is going on, our runner at third is looking to score.
As bad as I hate to admit it, I picked this up from a coach in CA (us TX guy don't like to admit that some of the west coast guys have it going on) several years back and we have been extremely successful doing it over the years.
