This situation has just happened recently so I haven't asked anyone in the association. I'll ask one of them tonight that I am working with. I was just curious what you all do. I guess I am the one getting burned because I am not covering properly. I was the BU both times this has happened and I assumed (I know, terrible word to use) the PU would rotate over the third. He did not, in both cases, and I made the call at third way out of position but I sold it well.
If I am the PU, I always rotate to third. Which I now realize is the wrong mechanic. Thanks for the clarification gentleman!
