The Padres have acquired Pedro Ciriaco from the Red Sox in exchange for a player to be named later, tweets Peter Gammons of the MLB Network. The 27-year-old infielder was designated for assignment by the Red Sox on Monday. Because he is out of options, Ciriaco will need to be placed on San Diego's 25-man roster.

Ciriaco hit .293/.315/.390 in 272 plate appearances for the BoSox last season, but batted just .216/.293/.353 in limited playing time this year. The signing of Stephen Drew and the emergence of Jose Iglesias made Ciriaco expendable to the Red Sox.

San Diego recently lost Jedd Gyorko to the disabled list, so it makes sense that the Friars were on the lookout for infield help. In 370 Major League plate appearances, Ciriaco is a .287/.315/.398 hitter. He has extensive experience at third base, shortstop and second base, but Ciriaco also played all three outfield positions and first base as well during his Red Sox tenure.
