The Red Sox are likely to activate left-hander Franklin Morales off the DL on Tuesday, manager John Farrell told reporters on Sunday. The southpaw will work out of the bullpen. Morales, 27, opened the year on the DL due to a bulging disc in his lower back. His 2012 season ended in late August thanks to shoulder fatigue. He's also had forearm, hamstring and other shoulder issues in the past.
