The Detroit Tigers just made a bold move to stabilize the back end of their bullpen. They signed veteran reliever Kenley Jansen to a one-year, $11 million deal with an option for 2027.
Let’s break down what Jansen brings to Detroit. How has his profile changed with age, and what could his arrival mean for manager AJ Hinch’s late-inning strategy?
Kenley Jansen to Tigers: A Future Hall of Famer in Detroit
Kenley Jansen isn’t just another veteran arm. He’s one of the most accomplished closers in modern baseball history.
At 38, he arrives in Detroit with a résumé most relievers would dream of. His track record suggests he can still impact the late innings in a big way.
A Closer with Historic Credentials
Jansen’s 476 career saves over 16 seasons put him fourth on the all-time list. Only Mariano Rivera, Jeff Hoffman, and Lee Smith have more.
That company says a lot about why this move matters for Detroit. They’re betting on a pitcher with a Hall of Fame trajectory and a knack for closing out big games.
From ages 32 to 37, when most relievers start to fade, Jansen kept producing. Over the past five seasons, he’s averaged:
Those numbers show durability and reliability. The Tigers have been searching for both to lock down the ninth inning.
The Art of the Cutter: Jansen’s Signature Weapon
Even as the league changes, Jansen’s identity stays the same. He’s a cutter specialist who challenges hitters in the zone and dares them to square him up.
Dominance Built on One Elite Pitch
Jansen’s main weapon is his 93-mph cutter, a pitch that’s frustrated hitters for over a decade. Last season, he leaned on it more than ever, throwing it a wild 81% of the time.
Even though hitters knew it was coming, they managed just a .164 batting average against it. That pitch still works when he commands it.
His ability to repeat his delivery and keep that late, cutting life on the ball has let him stay effective longer than most. Still, the data says the Tigers will need to manage him carefully.
Signs of Aging: Risk Beneath the Résumé
No 38-year-old reliever is a sure thing. Jansen’s raw stuff remains, but some numbers show the wear of 16 big league seasons.
Declining Strikeouts and Rising Hard Contact
Last year, Jansen posted a career-low 24% strikeout rate and a 25.8% whiff rate. Those are decent, but for a closer who once overwhelmed hitters, it’s clear his margin for error is thinner now.
The contact trends are a little worrying. In his most recent season, he allowed:
When hitters make contact, it’s often loud. The Tigers saw that for themselves on May 2, when they tagged Jansen for three home runs in a six-run inning—a nightmare frame that made people wonder how much he had left.
Resilience and Rebound: Why the Tigers Still Believe
What makes Jansen’s profile interesting is how he bounced back after that ugly outing in early May. Instead of spiraling, he recalibrated and delivered like the closer he’s always been.
A Dominant Finish to the Season
In his final 53 games, Jansen was downright elite:
The Tigers are banking on that stretch—a veteran who knows how to adjust, who’s seen every high-pressure scenario, and who can still lock down games when his mechanics are in sync.
How Jansen Fits in AJ Hinch’s Bullpen Strategy
Under manager AJ Hinch, the Tigers have moved away from the old-school, label-driven closer role. Hinch prefers to play matchups, using his best arms where the game is most at risk, whether that’s the seventh, eighth, or ninth inning.
A Three-Headed Late-Inning Monster
Jansen joins a late-inning trio with Will Vest and Kyle Finnegan. Finnegan recently signed a two-year, $19 million deal, giving Detroit another reliable option for high-leverage moments.
Vest brings versatility and some real swing-and-miss stuff for those middle-to-late innings. That’s a mix most managers would love to have.
Instead of pushing Jansen to pitch three days straight or chase save numbers, Detroit can use him more strategically:
This setup helps protect Jansen’s arm and lets the whole bullpen shine. For a Tigers team with playoff hopes, having that blend of experience and flexibility in the late innings might just tip the scales when it matters most.
