The White Sox declined Stassi's $7.5 million club option for 2025 on Friday.
Stassi will be paid a $500,000 buyout and is now a free agent. The veteran catcher has not played in the majors since 2022, as he missed all of 2023 due to a hip injury in addition to a family medical issue and then all of 2024 (aside from five rehab games) before having left hip surgery in June. It's not clear what Stassi's current health status is.
