The Detroit Tigers had a $3.1 million club option for Casey Mize\u2019s 2025 season built into his previous contract \u2014 a carryover from his pre-arbitration deal structured to cover his post-Tommy John return year. Declining that option was a signal that Detroit wanted to re-set his value through arbitration instead of committing early.<\/p>\n
The Tigers likely believed Mize hadn\u2019t yet proven durable or consistent enough in 2024 to justify locking in that $3.1 million figure, and that they could re-negotiate for less. However, it turned into a classic example of how trying to \u201csave\u201d a little money in the short term can cost much more in the long run.<\/p>\n
When the sides went to exchange numbers before a hearing, Mize\u2019s camp filed higher than Detroit\u2019s initial offer, and the sides settled at $2.34 million \u2014 about $760,000 less than the option they had declined. On paper, that looked like a small \u201cwin\u201d for Scott Harris and the front office.<\/a><\/p>\n But arbitration works on year-to-year escalation: every new salary builds on the last. By resetting Mize’s base lower in 2025 rather than keeping the $3.1 million option, the Tigers reset his future arbitration platform artificially low \u2014 yet Mize\u2019s actual performance in 2025<\/a> (healthy season, mid-rotation stability, innings volume) drove his 2026 projection up to $5.4 million anyway.<\/a><\/p>\n Had Detroit simply exercised the option, Mize\u2019s 2026 figure would have escalated from a higher starting point, but the total cost across both years would almost certainly have been smaller because of compounding percentages.<\/p>\n Inside the math of the miss on Tigers’ contract negotiations with Casey Mize<\/p>\n
