Hudson is a full participant in spring training for the Diamondbacks this spring, marking the first time since 2012 that he's been able to go through drills without restrictions, the team's official site reports. While Hudson is currently being stretched out as a starter, he may land in the bullpen between now and Opening Day. How he responds and the level of his performance during the Cactus League slate may ultimately determine his role, but at the very least a return to the mound after a brief taste of the big leagues in September will offer up a nice story since he's had two career Tommy John surgeries.
