Tejada isn't available yet according to what various credible people are saying. Even if he was, I doubt we have anything they want. Yea, they lost Ryan, but they're in the same mindset as us that they can plug anyone in a t closer (they have a 23-year old setup man they think could be the real deal).
We'd have to give up offense to get Tejada, something we don't have (unless they are looking for a salary dump, although we don't have much of that either).
