Jimenez was optioned to Triple-A Toledo on Saturday.
Jimenez closed out nine games in 2019 and led the Tigers with five saves in last year's shortened season, but he will not be part of the late-inning mix to open the 2021 campaign and will not even break camp with the big club. Jimenez figures to be called up at some point this season, but he presumably will need to show some results before being considered for save opportunities again.
