Marinez signed a minor-league contract with the White Sox on Monday.
Marinez will make his return to the affiliated ball for the first time since 2018 after spending the past three years with three different Mexican League clubs. The 33-year-old right-hander has previously made 103 career MLB relief appearances between seven different teams, posting a 3.56 ERA and 1.50 WHIP. He's expected to open the 2022 season at Triple-A Charlotte in the White Sox organization.
