The Cardinals will decline Gibson's $12 million club option for 2025, Derrick Goold of the St. Louis Post-Dispatch reports.
He will be paid a $1 million buyout instead and allowed to test free agency. Gibson, 37, had a solid 2024 campaign during his lone year in St. Louis, collecting a 4.24 ERA and a 151:68 K:BB over 169.2 innings covering 30 starts. However, with the Cardinals looking to trim payroll they've elected to move on from the veteran right-hander.
