VerHagen (shoulder) recently threw a pair of bullpen sessions and didn't report any soreness, Anthony French of the Detroit Free Press reports.
This is a big step forward for VerHagen, who threw off a mound for the first time since undergoing thoracic outlet syndrome surgery last July. VerHagen struggled before the surgery last season, but he posted a 2.05 ERA across 26.1 MLB innings in 2015 and could be a useful member of the Detroit bullpen if his rehab continues to go well.
