Taylor Teagarden's contract has been purchased, per the S-T, and Kam Loe is being sent down to make room for him.
Hank Blalock is also supposed to be activated today, and presumably, Joselo Diaz is being sent out to make room for him.
If Diaz is DFA'd, the there's no need to make room on the 40 man roster for Teagarden, since he can take Diaz's slot. If Diaz is just optioned, or if Diaz isn't sent down, then presumably Jason Jennings will move to the 60 day d.l.
UPDATE -- As expected, Loe has been optioned and Diaz DFA'd.
