Add a FA bat: C Davis or Dukes?

[Ballpark Frank]

I have an extra spot to add a bat. The players defensive position is of no importance, so who would you rather have for the stretch: Chris Davis or Elijah Dukes?

Thanks. Will try to help if I'm still in the neighborhood.

Hmmm...well, Dukes is back in the bigs and batting 6th today for the Nats. Anyone get positive vibes about either of these K machines for the rest of the season?

what are the other options on the wire? i'm not high on either of these guys.
