2019 Fantasy Outlook
Duffey spent more time in the minors than the majors last season as he appears to be out of Minnesota's long-term plans despite stretches of being productive as a reliever in 2017. Duffey is likely on the outside looking in for a spot in Minnesota's bullpen, especially since he has a minor league option left. He's likely candidate to provide depth and be shuttled up-and-down from Triple-A. Read Past Outlooks
$Signed a one-year, $557,500 contract with the Twins in March of 2018.
Records 13th hold
PMinnesota Twins
September 17, 2019
Duffey threw two-thirds of a scoreless inning to record his 13th hold in Monday's win over the White Sox.
ANALYSIS
Duffey has turned around his career at age 28, as he's gone from a player bouncing between Triple-A and the majors (and between the rotation and bullpen) to a key setup man. Duffey has dramatically improved his strikeout rate to 12.4 K/9. While his 3.25 FIP suggests his 2.47 ERA may be a little lucky, his career-high 93.9 mph average fastball points to an improvement in his skill and approach.

Stat Review
How does Tyler Duffey 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.
  • K/BB
    Strikeout to walk ratio.
  • K/9
    Average strikeouts per nine innings.
  • BB/9

Past Fantasy Outlooks
2018
2017
2016
Duffey moved to the bullpen last season after struggling as a starter in 2016, and he showed signs of improvement despite declining late in the season. Duffey had a 2.10 ERA in his first 17 outings, but a 6.55 ERA after May 30. He may have been somewhat unlucky as he had a 3.76 FIP compared to his 4.94 ERA. He increased his velocity (92.1 mph average fastball compared to 90.4 in 2016) and had a career-best 8.5 K/9. Duffey's downfall has been problems with the long ball despite good control (2.3 BB/9). Duffey isn't likely to return to the rotation and may be limited to middle or long relief if the Twins improve their bullpen by adding pitchers with more velocity.
Duffey took a big step back last season after a strong rookie year, leaving his status in the major league rotation in doubt. He looked set to be a solid starter in the majors after posting a 3.10 ERA with a strong 8.2 K/9 in the second half of 2015. Duffey's sharp curveball with a 12-to-6 break compensated for his lack of velocity (90.2 mph average fastball) in his rookie season, but major league hitters figured out the pitch last season. He also struggled against right-handed batters by allowing a 1.038 OPS to righties compared to allowing just a .738 OPS to righties in 2015. He may have been a bit unlucky with a 19.5 percent HR/FB rate (3.89 xFIP). Despite his struggles, he still had a decent 7.7 K/9 and good control (2.1 BB/9), so there's hope for a turnaround. However, he'll need to win a spot in the rotation this spring and may need to prove himself again in Triple-A.
Duffey wasn't considered a top pitching prospect before last season, but he was called up to the majors in July after posting a 2.53 ERA with a 7.2 K/9 at Triple-A. In fact, he may have been Minnesota's best pitcher in the second half of the season as he had a 3.10 ERA with a strong 8.2 K/9. Duffey has an outstanding curveball with a 12-to-6 break that compensates for his lack of velocity (90.2 mph average fastball). He's also been able to keep the ball on the ground (49 percent groundball rate) and in the park. Duffey should enter the spring as the No. 3 starter and could be a sleeper in most fantasy leagues.
