As a Rays fan, I am nothing short of ecstatic about seeing him pitch. Apparently he's going to be in a relief role, ala David Price in 08'. Should be very good to see, hopefully he's a relief ace.
Also, hopefully he pitches lights out so he makes our FO think he can start opening day in 2012. But knowing our FO, probably not going to happen, since we still need to free up a spot in the rotation, plus do something about Alex Cobb when he's healthy.
