Drey Jameson

After missing the entire 2024 campaign while recovering from Tommy John surgery, Jameson was back to full health for the start of the 2025 season, but was limited to just three appearances for Arizona and 16 in the minors. Unfortunately, the hard-throwing righty was shut down in late June when he developed a bone fragment chip in his surgically repaired elbow. The 28-year-old didn't return to action before the end of the minor-league season, but managed to avoid another procedure on his elbow. Jameson appears to be in line for a normal offseason following his recent return to action in the Arizona Fall League. Given he maintains a spot on Arizona's 40-man roster, Jameson is expected to compete for a bullpen role this spring. With an upper-90's fastball, strikeout upside and a high groundball rate, he fits the typical closer profile, but whether that will translate to save chances with the D'Backs will largely depend on his health and performance.
