After leaving the Dodgers, Jansen spent one season with the Atlanta Braves and then two seasons with the Boston Red Sox.
The right-hander spent last season with the Los Angeles Angels and posted a 2.59 ERA – his best mark since his final season with the Dodgers in 2021 – in 62 appearances. He recorded 29 saves in 31 chances in 2025, and had an 11 scoreless streak midway through the season. He earned his first American League Reliever of the Month award in July.
Detroit struggled with their bullpen in 2025, finishing the season with the 17th best ERA in the league among their relievers. Will Vest served as their primary closer last season and while he had a decent 3.01 ERA in 64 appearances, he struggled in high-leverage situations, blowing seven of his 30 save opportunities.
