Fiers (elbow) signed a contract March 24 with Leones de Yucatan of the Mexican League.
Fiers made just two starts for the Athletics in 2021 after suffering a sprained right elbow in early May and experiencing multiple setbacks during his rehab. The 36-year-old right-hander is seemingly healthy again, but he's still likely to need a strong showing in Mexico just to secure a minor-league deal with an organization.
