(Reuters) - The Boston Red Sox added some bench strength by acquiring first baseman/outfielder Mike Carp from the Seattle Mariners on Wednesday in exchange for a player to be named later or cash considerations.

The lefty hitting Carp is coming off an injury-plagued season in which he appeared in just 59 games hitting .213 with five home runs and 20 RBIs.

Carp, 26, showed promise as a rookie in 2011, hitting .276 with 12 home runs and 46 RBIs in 79 games.

Off-season additions of Kendrys Morales, Michael Morse and Raul Ibanez cut into potential playing time for Carp in Seattle.
