According to Greg Schaum of KCSP 610 radio in Kansas City, the Royals have designated catcher Brayan Pena for assignment to clear roster space for Jose Guillen. Pena, 27, was 2-for-7 this season with one RBI. With Miguel Olivo and John Buck splitting most of the time behind the plate, he was a bit of a misfit.
