The Chicago White Sox have placed relievers Matt Thornton and J.J. Putz on the 15-day disabled list, leaving their bullpen a bit short on experience.

They recalled right-hander Lucas Harrell from Triple-A Charlotte and reinstated lefty Erick Threets from the disabled list following a rehab assignment with the minor league club before Wednesday's game against Baltimore.

Thornton, an All-Star, was placed on the DL retroactive to Aug. 18 because of inflammation in his left elbow. He is 3-4 with a 2.66 ERA and leads AL relievers with 66 strikeouts.

Putz, who left Tuesday's game against the Orioles because of right knee tendinitis, is 6-5 with a 2.68 ERA.
