Tigers Have A Bullpen Problem And A Few Very Different Fixes

The Detroit Tigers are eyeing key trades to bolster their bullpen and transform last season's missed opportunities into winning plays.

The Tigers’ offseason problem is bigger than finding another bat. Detroit spent 2026 with a bullpen that too often let leads slip away, and that reality has to sit near the top of Scott Harris’ winter checklist.

The numbers tell the story plainly. Detroit went 76-86, and its relievers finished with 32 saves and 32 blown saves. That second total included chances before the ninth inning, so it did not mean 32 separate losses, but it still underscored the same issue: the late innings were not reliable enough.

That’s why Harris should be looking beyond free agency and into the trade market. There are different ways to attack the problem, and three pitchers stand out as possible fits: an established closer, a controllable arm with something to prove, and a steady setup piece who could help keep games in hand before the ninth.

Aroldis Chapman is the most obvious name if Detroit wants the quickest fix. The Boston Red Sox left-hander put together a dominant 2026 season, posting a 1.92 ERA with 35 saves and 71 strikeouts in 51 2/3 innings. His 2027 salary is now guaranteed at $13 million after he cleared the innings threshold and passed his end-of-season physical, and he’ll turn 39 before Opening Day.

Boston’s need for more offense could create the kind of opening Detroit would have to explore. A deal built around an affordable hitter, plus a secondary prospect, would make sense as a starting point if the Tigers took on the money.

The Red Sox could ask for more if they don’t have a strong replacement lined up, but Detroit shouldn’t be talking about any cornerstone prospect here. Chapman is worth checking on as a one-year answer, not a franchise-altering gamble.

Riley O’Brien offers a different kind of appeal. The St.

Louis Cardinals right-hander saved 38 games and struck out 64 batters across 64 innings in 2026, and he comes with four more seasons of club control. That gives Detroit a longer runway if it believes in the arm.

Still, the performance comes with real questions. O’Brien finished with a 4.08 ERA, and his second-half ERA rose to 5.11.

The Tigers would need to dig into his late-season velocity drop before moving forward. St.

Louis may also be willing to listen, especially with the Cardinals focused on younger talent and O’Brien turning 32 in February. A pitching prospect from the middle of Detroit’s top 30, along with another developmental player, would be a logical place to start.

But the price has to match the risk. The Cardinals can just as easily hold onto an inexpensive closer if the return isn’t right, and Detroit should be just as careful.

Kevin Kelly is the cleaner fit if the goal is to strengthen the bridge to the ninth rather than solve everything with one move. The Tampa Bay Rays right-hander turned in a 2.44 ERA and 0.90 WHIP over 73 2/3 innings in 2026, striking out 63 and walking only 11.

That kind of command plays anywhere, and it would help A.J. Hinch protect leads before the closer takes over.

Kelly wouldn’t replace the need for another ninth-inning arm by himself. He would complement one.

Tampa Bay’s run to the ALCS means the Rays have little reason to move useful pitchers cheaply, and Kelly’s control through 2029 gives them leverage. Detroit would likely have to offer a controllable hitter ready for the Majors, with a secondary prospect depending on the hitter’s value.

Of the three, Chapman is the first call because he addresses Detroit’s most obvious weakness most directly. Kelly makes sense as a support piece if the Tigers want to build a stronger bullpen around that.

O’Brien is the lower-cost, longer-control option, but only if the asking price stays in check. However Harris approaches it, the mission is clear: build a bullpen that can hold a lead across several innings, not just the final three outs.

Tigers May Have Found A Draft Bat Fans Shouldn't Overlook

Scott Harris has taken his share of heat for the Tigers uneven season, but the one area where Detroit has earned more trust is the draft. The farm system has started to look deeper in part because of recent selections, and one of the names drawing attention is Will Adams, the 11th-round pick in the 2026 MLB draft. He arrived with a reputation that far outpaced his draft slot, which is part of why the pick has started to look like a possible steal.

Adams had long been viewed as more than a late-round flier, and he also gave Detroit something it does not always get in that range by choosing to sign rather than head to LSU. Baseball America has gone a step further, putting him among the better pure hitters in the class because of the way he combines bat-to-ball skill with power. For a Tigers organization still trying to build a sturdier talent pipeline, that kind of offensive profile is exactly the sort of upside that can make an overlooked pick turn into a real development story.

Jace Jung Is Fueling A Tigers Debate Scott Harris Can't Ignore

The Tigers recent front-office philosophy under Scott Harris has leaned heavily toward keeping premium young talent in the organization rather than using it as trade currency, a approach that fits a club trying to build patiently through the system. Jace Jung, the 2022 first-round pick, has become the kind of case that makes that strategy harder to defend, because Detroit has been asking fans to wait on a prospect whose development has not yet matched the pedigree.

Jungs rocky path has turned him into more than just one players story. It has become part of a broader debate about whether Detroit should be more open to moving prospects when the fit is unclear, instead of treating top names as untouchable. For a team still trying to sort out its next competitive core, the question is whether holding on too long is really the safer play. [Read more 🡒]

Tigers Offseason Should Start With One Clear Building Block

The Tigers were out of playoff contention long before the seasons final stretch, which has pushed the conversation in Detroit squarely toward what comes next. In that space, rookie Kevin McGonigle has already made a strong case to be part of the answer, giving the club useful production on both sides of the ball and a promising look at a young player who can matter beyond a single season.

McGonigles emergence puts a real shape to the offseason for a front office that has to decide whether to lean into its younger core or make bigger roster changes elsewhere. For a team that spent too much of the year looking up at the standings, the appeal of a clear building block is obvious, and the Tigers now have one player who makes that path easier to imagine even as the rest of the puzzle remains unfinished.
