One DL spot: Delgado or Dice K?

[Ballpark Frank]

I only have DL space to keep one: Of the guys on my roster, should I stash Delgado or Dice K? At this point, their positions are meaningless. I'm just looking to keep the guy that has the most potential down the stretch. Either one of these guys stand out above the other? Will help if I'm still in the neighborhood.

dice k for sure most potential here.
