Looked like he strained something. It showed a replay of the nothing fastball and he winced during the motion. They don't want to aggravate any injuries.
I'm really liking A.J. Pierzynski, he reminds me of a guy
that used to kill us in softball. Same look when he's at
the plate. I know that look, seeing as how he probably had
an .850 batting average against me....LOL
