Andrew Suarez
While it's not clear who the Cardinals will rely on from the left side out of their bullpen in 2024, Andrew Suarez will not be a part of that conversation.
In 13 games, Suarez posted a 7.16 ERA in 27.2 innings of work, and over the course of four seasons in the Majors, he's sitting on a career 4.96 ERA.
John King and JoJo Romero are the two front runners for left-handed bullpen opportunities in 2024, while names like Zack Thompson, Matthew Liberatore, or Drew Rom could factor in as well. I also imagine that St. Louis will target a left-handed veteran in their efforts to rebuild their bullpen this offseason, so I do not see why Suarez would return in any capacity for them.
