I am glad for Pena. It would have been nice to get a Class A player in return but Pena doesn't have much value.
Danny Mac let slip on air the other day they allegedly the Cardinals got Jose Martinez for $1 from the Royals, so that could be what "cash considerations" means.
Which is hilarious, because in most of these cases the player is on Pena's level, which is "only break glass in case of emergency". Jose Martinez is a legit starting quality major league player for $1!
