Middlebrooks opened the season as the Red Sox starting third baseman, but struggled offensively, hitting .192/.228/.398 in 216 plate appearances. Jose Iglesias replaced Middlebrooks as the everyday third baseman, and Boston optioned Middlebrooks to Triple-A.
Boston manager John Farrell discussed the decision to bring Middlebrooks back with Maureen Mullen of CSN New England, telling the reporter:
"We feel like we have the potential to add a power bat to the lineup He's put himself in a better position to hit over the last 7-10 days, getting a little bit more squared up with his stance in the box."
Middlebrooks looked better in Triple-A, but did not dominate, batting .268/.327/.464 in 196 plate appearances.
Snyder, hitting .209/.227/.419, is battling a right elbow injury. The Red Sox made the move retroactive to Aug. 8.
