Humber signed with the Padres on a minor league contract Thursday, Matt Eddy of Baseball America reports.
Humber, who has not pitched at the minor league level since 2013, spent all of last season with the Kia Tigers of the Korean Baseball Organization. He'll make an attempt to stick with the Padres system as a 33-year-old right-handed reliever, though he'd be considered a long shot to make the 25-man roster out of spring training.
