Twins call up Kevin Mulvey

La Velle E. Neal III of the Minneapolis Star-Tribune is reporting that the Twins have called up right-handed pitcher Kevin Mulvey from Triple-A Rochester while optioning catcher Jose Morales. Mulvey, who came over to the Twins for Johan Santana, is 3-6 with a 3.93 ERA this season in the Red Wings'rotation.The first thing that came to my mind is that the Twins are showcasing him to potential buyers. It kind of stacks up with the Alexi Casilla promotion. Although that one made more sense, the Pirates are looking for a player to replace Freddy Sanchez and a couple pitching prospects. Mulvey doesn't figure to fit in long-term, so perhaps this could be a way for the Pirates to see him at the Major League Level.We'll see.
