Smith (forearm) threw out to 120 feet Tuesday and will need to repeat that before pitching off a mound in the bullpen, the Boston Globe reports.
Smith has been placed on the 15-day disabled list with a flexor-muscle strain that cropped up Mar. 21 and does not have a timetable for his return. Injuries like his can take anywhere from a month to two months. In the meantime, the Red Sox have Matt Barnes in the bullpen to replace his innings.
