"That went fine," Yankees manager Joe Girardi said. "He'll probably have something every day; it'll continue to progress, but he did start his throwing program today."
Hughes has been on the disabled list since April 15 with what the Yankees have listed as right shoulder inflammation, though the right-hander was sent to a St. Louis-based specialist to determine if he was suffering from thoracic outlet syndrome.
The team has expressed optimism that Hughes, 24, could be back on a mound within eight weeks. He had a 13.94 ERA in three starts, suffering from a drop in velocity.
