I don't think ownership is an issue in this case. I get that there is a large percentage of fans that want the back up CF to be a glove first player. It's fair, it's just not what I want.
But those guys are cheap regardless of ownership's prerogative. Even the Pirates can afford to pay defensive only players. There just aren't enough offensive capable CFs in the league; if you can hit and play a passable CF, you're going to be a starter.
With Buxton often injured, I want a guy with a bat to be the backup option, even if he turns the stomach of the defensive crowd. And if you can't get the surefire bat, give me anybody with the upside for a impact bat. So at this point, I'm OK going with Castro as the backup. I don't have high hopes for Martin, but at least there is a hint of potential. Of course the real goal is for E-Rod to be that guy. Signing a vet like Bader is going to significantly reduce that chance.
