You only bench a guy as a statement when he is being a malcontent so I am guessing it's just a Dee move. I would hope they wouldn't put Castellanos against a righty like Grienke.
can you get us this article on castellanos plz? http://www.baseballprospectus.com/article.php?articleid=17206
Castellanos is probably still on an airplane. It's standard procedure to throw a new call-up in the lineup before he has time to think about it, so if he's not in the lineup I'm guessing he's not physically there yet.
Oh cool, we're already down a run and it looks like Chad is going to give up some more because he sucks recently.
