I think he'll be good insurance to have at AAA for if Sano gets hurt. Miguel is usually good for an injury or two during the season, so having Rooker around to come up would be nice. If he comes up, he can find some things to work on when he goes back down. Later in the season he could be a good 26th man, then, and it hurts me on the inside to say this, Astudillo can go to AAA.
