After a visit to Dr. James Andrews, Fulmer underwent ulnar transposition surgery on his throwing elbow in September. Barring setbacks, the right-hander is expected to be ready for spring training. The Tigers hope the procedure will correct the finger numbness and hand weakness Fulmer experienced, which probably hindered his shortened sophomore season. Following his 2016 Rookie of the Year win, he endured notable dips in ERA (3.06 to 3.83), K/9 (6.2, after 7.5 in his first season) and left-on-base percentage (79.0 to 65.6 percent). Fulmer, who turns 25 in March, owns an alluring combination of top-end velocity and a career 2.3 BB/9, which could become even more valuable if health brings back at least his 2016 K/9 (7.5) and possibly pushes it higher. Still, if he impresses in March, his price might climb to where the reward won’t match the risk. Fulmer may not round into peak form until later in the season. Read Past Outlooks
