Buxton and Pineda to be activated today, with Donaldson coming on board tomorrow, according to MLB Trade Rumors. Who goes? I would guess that LaMonte Wade Jr. is certain to head back to St. Paul with Buxton being activated. As far as making room for Pineda, Minaya or Poppen would make sense. Perhaps "sending down" Poppen for a day, since an extra player will be required for the doubleheader on Thursday. Vargas would figure to be on thin ice for a DFA tomorrow.
Its not only who is sent to St. Paul. When Pineda is activated, someone is going to have to come off the 40-man roster also, unless there are some other injuries/illnesses that could be moved off the 40-man.
If they do DFA someone, not even going to try to guess who?
