Before grabbing Podsednik, I'd look at Matos.
If you sort by averages in Yahoo and then by rank, Matos ranks a surprising 3rd overall. That is 2nd for hitters, behind only Soriano! Matos will steal bases about as often as Pod, but should contribute in HR's and RBI's as well.
I doubt he puts up these stats the rest of the way, but 30 some games is a decent sample size, so he's worth a shot short term.
