JoJo Romero had a successful 2024 with 30 holds and a 3.36 ERA, but advanced metrics like his xERA of 5.14 raise concerns about potential regression. His sinker proved less effective, and that could lead to a decline in his ratios going forward.

JoJo Romero has emerged as a key trade candidate for the Cardinals this offseason. The 28-year-old setup man recorded a 7-3 record with a 3.36 ERA and a 51-to-16 strikeout-to-walk ratio over 59 innings pitched. With team control through 2026 and a projected market value of around $26 million over five years, trading Romero could help the Cardinals acquire valuable prospects as they look to rebuild their farm system. His departure would be a significant loss for the bullpen, where he played a crucial role alongside Ryan Fernandez and Andrew Kittredge in supporting closer Ryan Helsley.

Without Andrew Kittredge in the bullpen, the Cardinals will lose a key component of their relief core, which includes JoJo Romero. As the team looks to rebuild and potentially replace Kittredge with younger talent, Romero's role could become more significant in high-leverage situations alongside Ryan Helsley, the team's all-time saves leader.

JoJo Romero was placed on the 15-day injured list due to left forearm flex inflammation, retroactive to September 22. This move prompted the Cardinals to recall RHP Chris Roycroft from Triple-A Memphis to fill the roster spot.
