Drey Jameson

Arizona Diamondbacks reliever Drey Jameson could be a key piece of the team's bullpen in 2026 after injuries have left the staff thin, as A.J. Puk (elbow) is not expected to return until July and Justin Martinez (elbow) is targeting an August return. That leaves closing duties to the likes of Kevin Ginkel and Paul Sewald, who combined for five total saves last season, as Sewald dealt with a shoulder injury for most of the year and has been less effective since his 34-save campaign in 2023. Jameson may not get a crack at closing duties, but if he does, the right-hander has the stuff to be effective, including a fastball that can touch 99 mph. The former 34th-overall draft pick experienced elbow pain last year that caused him to be shut down in June, but he was able to strike out 19 batters in 12 2/3 innings pitched at Triple-A before that and was healthy enough to pitch again in the Arizona Fall League. The 28-year-old has looked good so far this spring, too, punching out three batters in two innings of work, with his four-seamer topping out at 98.7 mph. Jameson is not rosterable in most fantasy leagues at the moment, but he's a name to keep on the radar should Ginkel or Sewald falter early on.
