I shall tell you this now:
After today's game, the Diamondbacks outrighted infielder Sean Burroughs to make room on the roster for WIly Mo Pena, who they've called up.
Here is the official word I got, via Twitter:
#Dbacks outright Sean Burroughs after today's game to free up roster spot; 9 of next 12 games will be played in AL ballparks
Gang, you got your wish...it may not be Mora but it's one of a few people you were hoping to see gone...
