2019 Fantasy Outlook
The 2013 first-round draft pick has underwhelmed in his career, but showed some progress at Triple-A last year with a 3.98 ERA based on improved control (2.7 BB/9) and inducing ground balls (57.3 %). He surprisingly got a callup to the majors and did better than many expected. He had just a 5.9 K/9 and 4.4 BB/9, but again kept the ball on the ground (53.5 %). He also showed decent velocity (92.6 mph average fastball). While he wouldn't appear to have much upside given his spotty track record and lack of strikeouts, he could work his way into a bullpen role or add value as a long reliever. Read Past Outlooks

Demoted following win
PMinnesota Twins  AAA
May 11, 2019
Stewart (1-1) earned the win in Game 2 of Saturday's doubleheader against the Tigers but was optioned to Triple-A Rochester after the game, Dan Hayes of The Athletic reports.
ANALYSIS
Stewart's second major-league outing of the year went much better than his first, as he struck out two and allowed three runs on six hits and two walks over six innings. The 24-year-old will rejoin the Red Wings to make room on the roster for Sunday's starter, Martin Perez, who is coming off the paternity list.

Stat Review
How does Kohl Stewart compare to other starting pitchers?
This section compares his stats with all starting pitcher seasons from the previous three seasons (minimum 120 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 40 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
2017
2016
2015
2014
Despite his pedigree (No. 4 overall pick in 2013) and the impressive grades from scouts on some of his pitches, Stewart has been unable to miss bats at a level fit for a future mid-rotation starter. He started to change that narrative a little at High-A (20.8 percent K rate), but then he finished the season with just 47 strikeouts in 92 innings at Double-A. Stewart could still be a big-league starter, but there are no signs that he'll miss enough bats to be an exciting fantasy option.
Stewart, the fourth overall pick in the 2013 first-year player draft, saw his prospect status dip last season due to lack of strikeouts and mediocre command. Stewart had a 3.20 ERA at High-A Fort Myers, but just a 5.0 K/9 and 3.1 BB/9. Stewart has a mid-90s mph fastball, but it was his second season with a lackluster strikeout rate. While he keeps the ball down (54.8% GB%), opposing batters make too much solid contact against him. Stewart is just 21 years old, but will need to improve significantly to thrive at higher levels.
Stewart, the fourth overall pick in the 2013 draft, is regarded as one of Minnesota's top pitching prospects after a promising first full season of professional baseball. Stewart had a 2.59 ERA for Low-A Cedar Rapids and more than held his old as a 19-year-old. While his strikeout rate wasn't spectacular (6.4 K/9), there's reason to think it will improve since he hits 95 mph with his fastball. He also kept the ball on the ground with a 52 percent groundball rate and only four home runs allowed in 19 starts. Right shoulder inflammation ended his season in August, but Stewart is expected to be ready for spring training. He'll likely begin the season in High-A and could be on track to reach the majors as early as 2017.
Stewart, the fourth overall pick in the 2013 draft, had a strong professional debut, posting a 1.35 ERA and a 24:4 K:BB in 20 innings spanning seven appearances between Minnesota's two rookie-league teams. He was viewed as the top high school pitcher in the draft and an outstanding athlete, as the high school quarterback turned down an offer to play football at Texas A&M. He has a fastball that can reach the high 90s, which is the kind of velocity the Twins have been lacking in their system. Stewart was limited to rehab work during the Twins' instructional league due to a sore shoulder, but is expected to be healthy in the spring. He could begin his first full season with the Twins' Low-A Midwest League affiliate, but he seems unlikely to emerge in the big leagues before 2016 at the earliest.
