The Red Sox are overhauling their pitching staff, so the 25-year old might get a shot at earning a spot on the 25-man roster during spring training. Spruill can both start or relieve but is far more likely to become a middle reliever in Beantown.

Since the D'backs had designated Spruill for assignment earlier in the off-season, they did well to land a prospect in return. The 22-year-old Smith really struggled at low Single-A Greenville in 2014 but is still young enough to turn things around.

Spruill's fantasy value will likely decrease as a member of the Red Sox, as his chances of starting or playing a prominent bullpen role have diminished. As for Smith, he needs to prove he can pitch better in A-ball before becoming a fantasy factor for the future.
