At this time last year, most would have had trouble settling on their prediction for a Tigers Rookie of the Year prediction. Now a relative lock for the starting rotation, Spencer Turnbull was a victim of prospect fatigue and flew mostly under the radar. Zac Houston received some attention thanks to his track record of performance, but most fans have little faith in relief prospects. The most intuitive guess was Christin Stewart, an offensive prospect with power and patience who was given every opportunity to earn full-time reps.
Come the end of the season, the honor was handed to Harold Castro.
