Daniel Stumpf

The Tigers' bullpen is unsettled, and as they say, chaos is a ladder. Unfortunately, Stumpf does not have the skills necessary to climb that ladder. The 26-year-old lefty gained a tick of velocity in his first season in Detroit, but he still struggled to generate swings and misses. Stumpf posted a 7.4 percent swinging-strike rate and his O-Swing rate was under 30 percent -- he may have a hard time repeating his modest 7.8 K/9 from a year ago. He had a below-average walk rate (3.6 BB/9) and Stumpf struggled against right-handers (.360 wOBA), especially with the long ball (1.71 HR/9). The estimators all point to Stumpf being closer to a mid-4.00s ERA pitcher. As a holds play, Stumpf makes some sense, but there does not seem to be much room for growth in terms of role given his splits.
