Milwaukee Brewers pitcher Andrew Chafin
It has not been a good year for Chafin in split time with the D-Backs and Brewers, with a 4.73 ERA with 4.9 BB/9 in over 50 innings, but he has been a dependable late-inning lefty through most of his career.
Chafin has a team option for 2024 but if he becomes a free agent the Cardinals could be interested like they were last off-season. Despite a rough season for Chafin this year, he has shown in his 10-year career that he can get right-handed and left-handed hitters out, and pitch in high-leverage situations.
With Zack Thompson looking like he'll compete for a starting spot next year, Chafin is a significant upgrade over somebody like Andrew Suarez to join John King in that bullpen as late-inning lefties Oli Marmol can call on.
