23-Year-Old PitcherSP
2019 Fantasy Outlook
Sheffield might be best suited for a high-leverage relief role, but after getting traded to the rebuilding Mariners, he should get a fair audition in the rotation. He headlined that November trade that sent James Paxton to the Yankees. The industry consensus is that Seattle valued Sheffield and the rest of the haul more than most, so it would be a mistake to assume that trade validates him as a high-end pitching prospect. The 5-foot-10, 195-pound southpaw has a couple nasty pitches -- mid-90s fastball with life, plus high-80s slider -- but his changeup, command and pitchability all lag behind, hence the speculation he may be better suited getting outs in the eighth and ninth innings. The Mariners will likely send Sheffield back to Triple-A until they gain an extra year of control in late April and perhaps for several months as he works on smoothing his rough edges. He will be worth a flyer when he debuts, but is not stash-worthy in most formats. Read Past Outlooks

Wraps up season with no-decision
PSeattle Mariners
September 28, 2019
Sheffield gave up one run on five hits and four walks while striking out two over five innings in a no-decision against the A's on Friday night.
ANALYSIS
One run over five looks good at a glance, but he was walking a fine line with the four free passes and a homer allowed. Sheffield was probably due for a run of better luck after he had some unfortunate breaks against him in his prior two starts (9.35 ERA, 2.76 FIP in those two outings). The lefty ends the 2019 season with a 5.50 ERA and 1.72 WHIP in 36 innings with the big club, and should get a chance to compete for a rotation spot in spring training.

The fact that we all immediately think of the same handful of guys (Tim Lincecum, Johnny Cueto, Sonny Gray, Marcus Stroman) when trying to list recent pitchers under six feet tall who have experienced prolonged success in big-league rotations tells us how rare they really are. Sheffield, a 5-foot-11 lefty, has a chance to join that unique company in the coming years. He has a plus mid-90s fastball with late life, an above-average slider and an average changeup, but his command still needs some work. A strained oblique limited him to 98 innings -- the lowest full-season total of his career. This led to an assignment to the Arizona Fall League, where he logged a 3.10 ERA, 0.84 WHIP and 22 strikeouts over 20.1 innings. Many evaluators who saw him in the AFL said that was the best they had ever seen him pitch. He will start the year at Triple-A, and while he won't be rushed to the majors, he could get there on merit sometime this summer.
Sheffield came over to the Bronx Bombers from the Indians along with Clint Frazier as the second piece in the Andrew Miller deal. The southpaw has a live arm and finished the season on a high note. The 20-year-old posted a 1.73 ERA and 27:10 K:BB in 26 innings with High-A Tampa to end the 2016 campaign. Opposing batters hit a putrid .157 against him over that span. In fact, Sheffield has averaged more than one strikeout per inning throughout his brief time in the minors. Sheffield's control could use a bit of work. though: He walked 53 batters in 125.1 innings last year. In addition, he does not have the prototypical size of a future frontline rotation anchor at 5-foot-10, 195 pounds. Still, Sheffield possesses four pitches and has the tools to contribute in the big leagues as early as 2018. He should begin the 2017 season in Double-A Trenton.
After a red-hot finish to the season, Sheffield’s 2015 numbers leave very little to be desired. The 19-year-old southpaw distinguished himself as the top pitching prospect in the Indians’ offense-heavy farm system, but despite the gaudy strikeout totals in the lower levels, Sheffield probably only has the upside of a No. 3 starter in the big leagues. He has a mid-90s fastball, but neither his curveball or changeup project to be elite pitches. That said, the fact that he already has three above-average offerings with solid command separates him from most pitchers below Double-A, so his numbers should remain impressive at High-A in 2016. The elephant in the room is that Sheffield measures in at 5-foot-10, 196 pounds, and will likely always be discounted slightly due to his height until he shows he can succeed against big league hitters. Still, this is a starter’s profile, and one worth monitoring in most dynasty formats.
Based just on pure stuff and control/command, Sheffield, the 31st pick in the 2014 draft, profiles as a No. 3 starter in the big leagues. However, whether fair or unfair, the first thing that should be noted with the 18-year-old lefty is his height, or lack thereof, as Sheffield measures in at 5-foot-10. He appears to be able to make it work, featuring three plus pitches (fastball, curveball, changeup), but his height will be a bugaboo that follows him throughout his rise up the organizational ladder. Teams can always find a place for a bat-misser from the left side, but Sheffield’s worth in dynasty leagues is tied to his ability to stick as a starter. Fortunately, he has a thick frame (196 pounds), so he should be able to log the requisite innings. Sheffield will likely start 2015 in short season ball, meaning he won’t be in the big leagues until approximately 2018.
