The Tigers announced the release of veteran reliever Francisco Rodriguez on Friday.
Rodriguez, 35, has struggled for the Tigers this season, posting a 7.82 ERA in 28 games. In what would be his last appearance for the team, on Thursday night, he loaded the bases before giving up a grand slam to the Mariners' Robinson Cano.
In 2016, Rodriguez was effective as Detroit's closer, saving 44 games and posting a 3.24 ERA, but manager Brad Ausmus handed closing duties to Justin Wilson earlier this season. In his amended relief role, Rodriguez wasn't able to make enough of an impression to win the position back, and was vocal about his diminished role.
