2018 Fantasy Outlook
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. Read Past Outlooks

Goes two innings in start
PMinnesota Twins
September 11, 2018
Duffey allowed one run on two hits in a no-decision against the Yankees on Tuesday, striking out one and walking zero in two innings.
ANALYSIS
As anticipated, Duffey went just a couple innings (throwing 29 pitches) in his start and handed off the ball to long reliever Kohl Stewart. This was Duffey's first start of the year and his 15th appearance overall, and he now carries a 8.57 ERA and 1.29 WHIP with a 16:2 K:BB in 21 innings this season. It's likely the 27-year-old will be returning to the bullpen.

Past Fantasy Outlooks
2017
2016
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.
