Dodgers Sign Veteran Reliever Keynan Middleton to Minor League Deal

The Los Angeles Dodgers have added veteran reliever Keynan Middleton on a minor‑league contract, a move explicitly tied to bolstering Triple‑A Oklahoma City’s bullpen depth, with Baseball America’s Matt Eddy credited for the initial report as republished by MLBTR and other outlets. Sources differ on timing: RotoWire lists the signing as Feb. 16, while MLBTR’s story ran Feb. 27, 2026.

Middleton is a right‑handed relief pitcher who debuted with the Los Angeles Angels in 2017 and has since appeared for the Mariners, Diamondbacks, White Sox and Yankees. DodgersNation tallied his seven‑year major‑league totals at a 3.84 ERA over 205 appearances, with 199 strikeouts in 194.1 innings pitched. Early in his career he posted a 3.43 ERA with strong strikeout production across 76 innings in 2017‑18 for the Angels before undergoing Tommy John surgery in 2019.

His recent track record is a patchwork of flashes and medical setbacks. RotoWire credits Middleton with a productive 2023 aggregate: a 3.38 ERA with a 64:23 K:BB over 50.2 innings split between the White Sox and Yankees, while DodgersNation notes a tighter 1.88 ERA in the back end of 2023 with the Yankees. He reportedly signed a one‑year deal with the St. Louis Cardinals after 2023 but then sustained a spring right‑elbow flexor issue that required surgery in 2024. MLBTR reports that flexor surgery sidelined Middleton for the remainder of 2024 and nearly all of 2025; other outlets describe five rehab appearances in 2024 before the shutdown while MLBTR describes four minor‑league frames in 2024, highlighting a discrepancy in appearance versus innings metrics across reports.

Middleton attempted a comeback in independent ball late last season. MLBTR says he tossed 3 2/3 scoreless innings for the Atlantic League’s Long Island Ducks, while RotoWire lists him with four games for the Ducks in 2025. ClutchPoints and RotoWire frame those outings as the tail end of a recovery timeline that also includes prior injuries to his biceps, ankle, foot and shoulder.

The Dodgers view Middleton as organizational depth rather than an immediate major‑league addition. RotoWire and the original report fragment both state the signing "will give the Dodgers some experienced relief depth at Triple‑A Oklahoma City heading into 2026." DodgersNation further frames the move against a right‑hander‑heavy injury context: Evan Phillips and Brock Stewart are expected to miss Opening Day, leaving named healthy right‑handers Edwin Diaz, Blake Treinen, Will Klein, Edgardo Henriquez, Ben Casparius and Brusdar Graterol on the big‑league roster.

An ACES client with a history of high‑leverage strikeout stuff when healthy, Middleton’s path back is straightforward on paper: eat innings in Oklahoma City and show durable velocity and command after flexor surgery. If he can replicate the late‑2023 form that produced a 1.88 ERA in New York or the 3.38 season aggregate, the Dodgers have an inexpensive, experienced option ready to call up as bullpen insurance. How Middleton’s arm holds up in low‑leverage Triple‑A work this spring will determine whether this is a reclamation success or another depth signing.
