Tigers decline mutual option on Paul Sewald

The Tigers have declined their $10MM mutual option on reliever Paul Sewald, according to Evan Petzold of the Detroit Free Press. He will instead receive a $1MM buyout and become a free agent.

Sewald, 35, was acquired from the Guardians in July while he was rehabbing a right shoulder strain. The Tigers sent him on a rehab assignment in early September and activated him off the IL on September 18. He made his team debut the next day but only made four regular season appearances with Detroit, ultimately being left off the roster for the club’s playoff run. In 19 2/3 innings between the Guardians and Tigers in 2025, Sewald pitched to a 4.58 ERA while striking out 24.7% of hitters and issuing walks at a rate of 7.4%. While he has never been much of a ground-ball pitcher, he saw his ground-ball rate decline from 26.6% in 2024 to just 14.5% in 2025. His fastball, which he used 59% of the time this year, declined to 90.4 mph after sitting at 91.4 mph last year.

Mutual options are almost never picked up, so it was no surprise that the Tigers declined to bring back Sewald for $10MM given his injuries and underperformance this year. That said, he should garner plenty of attention on the market thanks to his track record. Between 2021-23, Sewald had a 2.95 ERA in 189 1/3 innings for the Mariners and Diamondbacks and posted a 25.3% K-BB rate that was tied with Jhoan Duran for 10th among qualified relievers. He also did well at limiting hard contact, with a better-than-average 85.9 mph in 2023. He was not as lucky in 2024. Sewald missed time with a left oblique strain and neck discomfort that year while posting a middling 4.31 ERA for the Diamondbacks.

Still, his track record from 2021-23 will be intriguing for teams seeking bullpen candidate. Sewald earned $7MM on his deal for 2025 and will be limited to a one-year deal given his age and recent injuries. Meanwhile, the Tigers will look to improve their bullpen after the unit finished 17th in the majors with a 4.05 ERA in 2025.
