The 21-year old Sheffield was listed as the third best overall left-handed pitching prospect just behind MacKenzie Gore of the Padres (1) and A.J. Puk of Oakland (2). The Yankees acquired Sheffield along with Clint Frazier and J.P. Feyereisen last July in a deal that sent reliever Andrew Miller to the Indians.

Sheffield is coming off of a 2017 campaign that saw him go 7-6 with a 3.18 ERA in 17 starts for Double-A Trenton. After an up and down first half of the season, Sheffield missed significant action due to an oblique strain that cost him nearly two months of action between July and August this past summer.

The Yankees summoned Sheffield to the AFL to get some extra work before shutting him down for the winter. In five starts for Scottsdale, the southpaw went 2-2 with a 3.10 ERA in 20 1/3 innings of work. He allowed 14 hits and fanned 22 batters while holding the opposition to a .192 batting average and got the starting nod in the annual AFL Fall Stars game; he finished second in the AFL in WHIP with a 0.84 mark.
