SEATTLE - Prior to tonight's game at Seattle, the Chicago White Sox returned right-handed pitcher Zach Putnam from his injury rehabilitation assignment at Class AAA Charlotte and reinstated him from the 15-day disabled list.
Putnam, 27, takes the roster spot of right-hander Andre Rienzo, who was optioned to Charlotte following last night's game.
Putnam has been on the disabled list since July 24 with right shoulder inflammation. He appeared in one game with Charlotte during his rehab assignment, working 1.0 scoreless IP with one strikeout on Tuesday night vs. Gwinnett.
Putnam is 3-2 with a 2.35 ERA (10 ER/38.1 IP), three saves, 32 strikeouts and a team-leading 12 holds in 33 appearances this season, his first with the White Sox. Twenty-three of his outings have been scoreless.
