Gregory Polanco is leading off tonight for Indianapolis against Syracuse, so it appears he hasn't been promoted yet. The idea was that he was going to travel to Pittsburgh today and join the Pirates tomorrow, but it now appears that at least the first part of that plan is highly unlikely. It is, obviously, not impossible that he could catch a plane in the morning.
I'm not even sure what I'm supposed to say about this anymore. The drama has gone on for months. Polanco will almost surely be up at some point in the next two weeks, but it looks increasingly unlikely that he'll be joining the Pirates tomorrow.
