Stephen Tarpley, 24, is the victim of pitching depth the Yankees have in the upper levels and is likely to be left unprotected. After missing the first half of the 2017 season, he came back, this time as a reliever and dominated in 14 games for the Tampa Yankees. In 30 2/3 innings in the Florida State League in 2017, he struck out 36 batters, walked 16 and allowed only four hits and no runs. He went on to make his Double-A debut on August 20, 2017, with two shutout innings.
With the Thunder, Tarpley appeared in four games, striking out 6 in 10 1/3 innings and allowing four runs and two walks in the regular season. He went on to throw just one shutout inning in the playoffs.
Tarpley sits in the low-to-mid-90s with his fastball. He backs it up with a curveball, changeup, and slider. His repertoire allows him to keep hitters guessing what is coming next.
