Hasn't he been terrible? I mean some guys just can't handle NYC. It isn't a bad thing to try to pick up those kinds of pieces who might thrive in a little less bright of a media glare.
It might still happen, but since it hasn't been announced, I don't think it is happening today. My guess is the send down happens after today game, with the call up officially on Monday.
So the thing is, Yermin doesn't have to go directly on to the major league roster at this point. The Sox already used his option, and that is good for the season, so they can just 40 man roster him, and send him to AAA.
