Benson, who has "capsulitis" inflammation in the capsule of his right shoulder, said from the D-backs' clubhouse on Tuesday that he received a second round of cortisone shots on Friday. Next, he will play catch on Saturday before throwing full-fledged bullpen sessions. Ultimately, the right-hander plans to return to Triple-A Reno for more rehabilitation outings.
Benson was placed on the 15-day disabled list almost immediately after straining his shoulder in an April 28 start against the Colorado Rockies. He made four rehab starts for Reno before suffering his latest setback.
"It turns out it was a little more serious than I thought when it first happened," Benson said.
