Montgomery is all fastball, as evidenced by his horrid results in Durham as a starter. He transitioned to relief in August where he focused on just throwing his plus-plus fastball and hard breaking ball, and that earned him a promotion to the Rays shortly thereafter, where he was able to max-effort his way into being an effective bullpen piece, with 93rd percentile fastball velocity and really good extension. The two-pitch combo is legit enough that he could be trusted with high leverage in 2025, provided batters aren’t barreling him up.
