The White Sox reinstated Leone (elbow) from the 60-day injured list Monday.
Leone had been on the shelf since May 20 due to right elbow inflammation, but he'll slot back into the White Sox bullpen after making four rehab appearances at Triple-A Charlotte. Before he was shut down with the injury, Leone compiled a 7.04 ERA in 15.1 innings. He'll likely have to settle for low-leverage work out of the bullpen now that he's healthy again.
