Who had March 12 in the Giambi injury pool?

Tyler Kepner tells us that Jason Giambi asked out of the Yanks’ trip to St. Petersburg today, citing a minor lower back issue. The Giambino has been known to aggravate his back in the past, especially when manning first base. He’s been doing this a lot during the spring. Hopefully, a day or so of rest gets him back on track.
