Per Richard Durrett, the Rangers have called up Kam Loe, purchased the contract of Joselo Diaz, and optioned Wes Littleton to AAA and Scott Feldman to AA.
The Rangers' 40 man roster is now full, with the addition of Diaz, although I can't imagine he'll be occupying a spot for long. But we now have a couple of fresh arms in the pen, should Luis Mendoza implode.
