The Rays designated outfielder Justin Ruggiano for assignment to create roster space for Carlos Pena, the Tampa Tribune tweets. The team's 40-man roster remains full.
Ruggiano appeared in 46 games for the Rays last year, playing all three outfield positions. The 29-year-old posted a .248/.273/.400 line in 111 plate appearances. Ruggiano, who also played for the Rays in 2007-08, is not yet arbitration eligible.
