Red Sox third baseman Pablo Sandoval is headed to the disabled list because of a left shoulder strain, the team announced Wednesday afternoon.
Infielder Josh Rutledge has been recalled from Pawtucket as a replacement.
Manager John Farrell said he couldn't pinpoint when Sandoval hurt the shoulder.
Sandoval had been supplanted in the starting lineup by Travis Shaw after a lackluster spring training. He has struck out in four of his six plate appearances so far this season.
