The Marlins have placed Jose Castillo on irrevocable waivers, according to MLB.com. Castillo had a decent spring and might get picked up, but he would probably end up as a back up elsewhere. He is a career .256 hitter with 33 HR in 465 games and could motivate a team like the Astros to deal Mark Loretta knowing they could bring him in as a replacement. Also, the Orioles are looking for a middle infielder and could go after him now that Uribe has been pulled from them. He played the outfield once last year and they could try and make him more versatile over time. I do not doubt he will be signed, but I think it might be when someone goes down or leaves through a trade.
