August 19, 2018
The Tigers recalled Stumpf from Triple-A Toledo on Sunday.
ANALYSIS
With righty reliever Buck Farmer moving into the rotation to make a spot start Sunday against the Twins, Stumpf will move up to the big club to give the Tigers another southpaw out of the bullpen. Over 41 appearances with Detroit this season, Stumpf has submitted a 7.11 ERA and 2.01 WHIP across 25.1 innings and will likely see his usage limited mainly to lefty-on-lefty matchups.

Stat Review
How does Daniel Stumpf compare to other relievers?
This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against this season's data (min 20 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Regan's Rumblings: Closing Time
August 3, 2017
Dave Regan shifts his rumblings toward exploring the ninth-inning pitching situation for each of baseball's 30 teams with the trade deadlne in the rearview.
Past Fantasy Outlooks
2018
2016
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.
Stumpf was the second player selected by the Phillies in the Rule 5 draft this winter. He spent the 2015 season with the Royals' Double-A affiliate in Northwest Arkansas. In 42 appearances out of the bullpen he managed a 3.57 ERA and 1.22 WHIP. Stumpf will get a chance to compete for a bullpen job with the Phillies this spring.
