Just reported by Buster Olney of ESPN:
Carlos Pena of the Cubs was claimed on waivers by an unknown team.
Well, what this tells us is... not very much. It could be a team from either league, although that would mean he would have passed through the entire National League. A waiver claim can mean one of three things:
(1) The player is pulled back from waivers, and nothing happens. In this event, the player cannot be put back on revocable waivers afterwards.
(2) The teams work out a trade within a 48-1/2 hour (business day) window. The claimed player may only be traded for players who have cleared waivers, or for players not currently on the other team's 40-man roster.
(3) The player and his entire contract are given to the claiming team for a $20,000 fee.
With the change to interim GM Randy Bush, it's possible the Cubs could deal him even if they want to re-sign him for next year -- though deals like that are pretty rare. Also, the return for Pena isn't likely to be very high, so whatever the Cubs would get back in trade isn't likely to be much.
So would you do it? Note that it would likely mean a month of Bryan LaHair at first base. (Not what I'd want.)
