J.J. Putz (forearm) will "probably" throw a simulated game on Monday before a return date is set, Diamondbacks manager Kirk Gibson said. Putz had scoreless rehab appearances on Thursday and Friday. Putz has been on the disabled list since May 5 with forearm tightness, but he appears close to a return. When he does, he'll likely return in a middle relief capacity until he proves worthy of a higher-leverage role.
