Starting pitcher Hiram Burgos was placed on the 15-day DL with a right shoulder impingement to make room for Gorzelanny on the roster.
Gorzelanny felt well enough to return from left shoulder tendinitis that a rehab assignment was not needed. He was placed on the DL on May 11.
Burgos had been bothered with the shoulder problem for some time and was trying to pitch through it.
"It has been bothering him some," Brewers manager Ron Roenicke said. "He didn't think it was to the point where he needed to say anything. He dealt with it last year. He said he thought it was similar to what he last year."
Burgos is not expected to miss a significant amount of time.
"We don't think it is that serious," Roenicke said. "So, hopefully, just a DL (stint) and he will be off in 15 days. That is we are thinking. Right now, that is what it should be."
Burgos is 1-2 with a 6.44 ERA in six starts this season. Mike Fiers (1-2, 5.93) will take Burgos' place in the rotation.
