The Twins claimed pitcher Jackson Kowar off waivers to bolster their bullpen ahead of the 2026 season.

The Minnesota Twins claimed right-handed pitcher Jackson Kowar off waivers from the Seattle Mariners on February 3, 2026, adding him to their roster ahead of the season. Kowar, 29, has 71 major league innings of experience, a history of injuries including Tommy John surgery, and a career 8.21 ERA in the majors. Out of minor league options, he cannot be sent down and may be assigned to the 26-man roster. The move fills a spot created by trading Edouard Julien and Pierson Ohl, aiming to strengthen a bullpen weakened by recent departures. While Kowar’s high-90s fastball and slider offer upside, his inconsistent performance raises concerns. The Twins view him as a potential late-inning option, though analysts say more proven relief help is needed.
