Well, more bad news for Yankees fans: It looks like Jorge Posada is seriously injured.

Via Pete Abraham's blog: The bad news for the Yankees is that Jorge Posada appears to have a serious hamstring injury. This strain is located above the last one that kept him out of the lineup for two days last week. He told the Yankees he felt something grab.

Posada will get an MRI today. The only other catcher on the 40-man roster is Francisco Cervelli, who is in AA. I would guess that the Yankees would call up one of the catchers from AAA and make a 40-man move.

With Kevin Cash on the DL in Scranton since April 4, one would suspect Chris Stewart would be the man to get the call from Triple-A -- in spite of the fact that he is hitting just .178 in 45 at-bats.

That's good news for former Thunder backstop P.J. Pilittere, who would become the starter by default. Pilittere is hitting .317/.349/.837 with Scranton, including .556 so far this month.

And where do the Thunder figure in all this, you ask? Well, that's unclear at this point, especially considering it might involve a 40-man move. If I had to guess, though, here's how I suspect it would play out:

The Yankees call up Stewart, necessitating a 40-man move, which my *TOTAL* guess would be Juan Miranda, based on questions involving his age and the fact that Mark Teixeira is locked and loaded for eight years. Then, Cervelli gets the undeserved but necessary call to Triple-A and Kyle Anson becomes the Thunder's everyday catcher, with Jose Gil serving as his backup.

The Thunder then are a man short, again, on their 24-man roster, which, based on how it has played out so far, is how I suspect it would remain for a while.
