CHICAGO -- The White Sox claimed right-handed pitcher Jose Ruiz off of waivers from the Padres, the club announced on Friday.
Ruiz, 23, was designated for assignment by the Padres on Dec. 15 after playing most of the 2017 season for Class A Advanced Lake Elsinore, going 1-2 with a 5.98 ERA, two saves and 45 strikeouts over 49 2/3 innings and 44 relief appearances. Ruiz was recalled by San Diego on July 24 and made his Major League debut in the ninth inning that evening against the Mets, where he threw one scoreless inning. Ruiz struck out Yoenis Cespedes and walked Asdrubal Cabrera during the frame.
Ruiz was optioned back to Lake Elsinore on July 25 for the remainder of the season.
The 6-foot-1, 190-pound Ruiz originally was a catcher before moving to pitcher during the 2016 season. He went 3-2 with a 4.79 ERA, four saves and 59 strikeouts over 62 innings and 55 career appearances in the Padres' organization.
With this move, the White Sox 40-man roster increased to 37.
