Kenley Jansen Lands with AL Contender, Wait–What This Means for Detroit and Boston
A former Red Sox closer is headed to another AL playoff hopeful. Reports indicate that Kenley Jansen has agreed to a one-year deal with the Detroit Tigers, pending a physical. ESPN’s Jeff Passan first broke the news, with MassLive’s Chris Cotillo noting that the teams were already deep in talks on the terms of the agreement on Saturday afternoon.
Jansen spent two productive seasons in Boston, posting a 3.44 ERA and 56 saves across 2023 and 2024. The Red Sox, buoyed by a late-year surge from veteran closer Aroldis Chapman in 2025, saw Jansen excel on a one-year contract with the Los Angeles Angels, recording a 2.59 ERA and a 0.95 WHIP this past season.
Across 16 big-league seasons, Jansen has established himself as one of the game’s most prolific relievers, owning a 2.57 ERA. He has been a four-time All-Star and has recorded at least 25 saves in 13 full campaigns, missing only the pandemic-shortened 2020 season.
With Jansen joining Detroit, the Tigers add another late-inning option alongside Kyle Finnegan, who re-signed for two years and $19 million earlier in the week. Finnegan, who flourished after a midseason move to Detroit, posted a 1.50 ERA with 23 strikeouts and four walks over 18 innings, then allowed three runs across six postseason appearances. He shared ninth-inning duties with Will Vest late in the season, but Jansen could emerge as the clearer closer for Tigers manager A.J. Hinch.
Detroit’s bullpen reshaping comes as the Red Sox shift focus away from high-profile relievers after signing Chapman to an extension late in the season. The current quiet on the trade and free-agent front around the Red Sox suggests a different strategic direction for the roster as they close out their postseason runs this year.
