Does your league only have one DL slot? I would hold on to Pedro or at least shop him around for a trade. You may be glad you kept him when playoff time rolls around (if your league has a playoff, which if it's Yahoo it does).
I'd contemplate trading for a more well-rounded source of steals than Podsednik -- you don't need to dominate in the category in H2H, just be competitive from week to week and you don't want him dragging you down in the other 4 categories (assuming 5x5 here).
Someone like Baldelli would be nice, or any decent 2B/shortstop with good speed ... Rickie Weeks, Josh Barfield, Rafael Furcal, Filipe Lopez, Orlando Cabrera. Maybe someone like Ryan Freel.
You can use your middle infielders, Podsednik, Pedro and maybe your bench (though it looks kind of weak to me) as trade bait. As long as the deal isn't too lopsided such a move could help you a lot.
At least that's how it looks from where I'm sitting.
