Kyle Finnegan's multiyear deal with Tigers makes sense

Originally posted on MLB Trade Rumors | By Anthony Franco | Last updated Dec 10, 2025 12:32 AM ET

The Detroit Tigers are reportedly bringing back veteran reliever Kyle Finnegan on a two-year, $19M contract. There are also $1M in bonuses available for the Warner Sports Management client. The Tigers' 40-man roster is full, meaning they’ll need to make a corresponding move once the contract is finalized.

It’s yet another domino to fall in a quick-moving relief market. Detroit initially acquired Finnegan from the Nationals at the trade deadline. He carried a 4.38 earned run average with a sub-20% strikeout rate at the time. It frankly seemed underwhelming for the team’s biggest bullpen pickup. The Tigers correctly identified Finnegan as a player who had another level of upside with a change to his pitch mix, however.

In Washington, Finnegan had thrown his fastball around two-thirds of the time. He used his splitter at a roughly 30% clip and sporadically mixed in a slider. The Tigers encouraged him to dramatically scale up the use of the split-finger offering. It was about a 50-50 divide in August, and he used the splitter more than 55% of the time in September and into the postseason. The impact on his results was immediate.

Finnegan allowed only three runs in 16 regular-season innings as a Tiger. He fanned 23 of 66 opponents, almost doubling his early-season strikeout rate. His swinging strike rate jumped by five percentage points. The righty secured four saves and three holds while surrendering just one lead. He missed a couple of weeks in September with a groin strain but immediately stepped back into a high-leverage role for skipper A.J. Hinch. Finnegan added 7 1/3 frames of three-run ball in the postseason, albeit with only three strikeouts.

Between the two teams, Finnegan posted a 3.47 ERA with a 24% strikeout percentage across 57 innings. The overall numbers aren’t far off the marks he’d carried over the first five seasons of his career. Finnegan entered 2025 with a 3.56 earned run average and a 23.5% strikeout rate in nearly 300 major league outings.

The altered pitch mix and the strong finish to the season have certainly changed teams’ perceptions of him. At this time last offseason, Finnegan found himself non-tendered by the Nationals in lieu of a projected arbitration salary around $8M. He waited until a week into spring training to return to Washington on a $6M contract with deferrals. Finnegan commands the first multiyear deal of his career one offseason later. The terms essentially match MLBTR’s prediction of two years and $20M.

Finnegan will again pair with Will Vest at the back of Hinch’s bullpen. He has plenty of closing experience from his time in Washington and could handle the ninth inning on days when the Tigers use Vest earlier in leverage situations. Detroit could stand to bring in another swing-and-miss arm at the back end. Even after acquiring Finnegan, the Tigers bullpen ranked 25th in strikeout rate. Assuming they build Troy Melton back up as a starter, Finnegan and Vest are their only two projected leverage relievers who sit around 96 mph on average. They’re a little light from the left side, but Vest and Finnegan each excel against opposite-handed batters. That could allow them to pursue another righty and stick with Tyler Holton and Brant Hurter as their top southpaws.

The specific salary breakdown is unreported. Evenly distributed $9.5M salaries would push Detroit’s projected payroll to roughly $157M, according to RosterResource. That’s about $15M north of where they opened this past season. The long-term books are still wide open. Javier Báez and Colt Keith are the only other players under contract for 2027. Keith’s respective $5M salaries for 2028-29 and modest option buyout in 2030 are their only commitments after the ’27 campaign.

Edwin Díaz, Gregory Soto and Finnegan came off the board on Tuesday. Robert Suarez, Brad Keller, Luke Weaver, Tyler Rogers, Seranthony Domínguez and Pete Fairbanks are the remaining unsigned relievers who made MLBTR’s Top 50 free agents. Keller and Weaver could get consideration as starters, while Rogers and Domínguez are setup types. Suarez is the best reliever still available. Fairbanks and Kenley Jansen join him as unsigned established closers.

Ken Rosenthal of The Athletic first reported the Tigers and Finnegan were nearing a deal. Robert Murray of FanSided had the two-year, $19M agreement with $1M bonus.
