The White Sox added more pitching to the organization Friday when they claimed right-hander Jose Ruiz off waivers from the Padres.
The Padres designated Ruiz, 23, for assignment Dec. 15 after he spent most of 2017 with Class A Lake Elsinore, going 1-2 with two saves and a 5.98 ERA in 44 relief appearances.
Ruiz made his major-league debut July 24 with an inning of scoreless relief against the Mets. The next day, he was optioned to Lake Elsinore for the remainder of the season.
The Venezuelan native signed with the Padres as an international free agent in July 2011.
