All three of the prospects acquired by New York project as relievers. The 22-year-old Callahan and his deceptive, over-the-top arm action had a dominant, walk-less month at Double-A to start the year before a promotion to Triple-A Pawtucket. Since arriving in Rhode Island, he has since struggled a bit with command. He has struck out 36 hitters in 29 innings at Triple-A, but has walked 13. He sits 94-97 and has a short, fringey slider in the 87-90 mph range, and a below-average change-up. Both secondaries project to average and Callahan projects in a middle relief role.

Bautista, a 22-year-old Dominican, is the most explosive of the three, sitting 95-99 mph and touching 100 with his fastball. He was signed back in April of 2013 at age 18 and then missed time that year due to a positive PED test. The following year, Bautista’s career began at age 19 in the Dominican Summer League and he has, more or less, been behind the developmental eight-ball since then. He owns a 5.16 ERA at High-A, largely because of wildness and ineffective secondary offerings — his slider flashes above average, but is mostly fringey, and the change-up is below average. But his arm strength is enticing.

Nogosek was a 2016 sixth rounder out of Oregon. He began his first full pro season as Low-A Greenville’s closer and dominated there until late June, when he was promoted to High-A Salem. Nogosek’s pitching regimen started to include multi-inning outings shortly before the trade. He struck out 18 hitters in 17.2 innings with Salem, walking 10. The righty sits 90-95 mph and will flash a plus slider. He pitches aggressively and projects to have average command.

Of the three, Bautista has the highest upside because he has the best arm. If he ever tightens up his slider he could be a set-up man. Callahan is, obviously, the closest to yielding major league value. Nogosek has the best secondary pitch of the group and the best command projection, too, and is probably the most stable long-term bet of the three, though his lower arm slot might cause platoon issues at upper levels and limit his role.
