Boston becomes Drew's second stop in the last four months, as the 29-year-old shortstop finished the 2012 season with the Oakland Athletics after being traded by the Diamondbacks in August.
Drew struggled last season hitting .223, with seven home runs and 28 RBI after returning from an ankle injury that he suffered in a home plate collision. The Red Sox are hoping that Drew can return to his pre-injury form and help buy their two top shortstop prospects -- Jose Iglesias and Xander Bogaerts -- some more time to develop. Iglesias has had trouble hitting at the big-league level, and Bogaerts appears to be at least a year away from joining the Red Sox.
Drew's brother, J.D. spent five seasons in a Red Sox uniform.
