Jarrod Saltalamacchia is in D/FW and will be active for tonight's game, per Jon Daniels (via the S-T).
No corresponding move yet to clear a spot on the 25 man for him, but my guess is that Luis Mendoza goes to the d.l., and they wait a day or two to see how Adam Melhuse is. If he's only going to be out a game or two, Salty gets sent back down in a few days to make room for another pitcher, and if not, he'll go to the d.l. and a pitcher will come up.
