Rodney threw off a mound at the Tigers' Spring Training complex in Lakeland, Fla., for about eight minutes. He tossed 35-40 pitches -- all fastballs and changeups -- at 80 percent intensity, according to head athletic trainer Kevin Rand.
It was a week ago Friday that Rodney had to be shut down from a similar side session with more shoulder soreness, the latest setback for the right-hander who was expected to be Detroit's eighth-inning setup man.
There's still no firm timetable for a return, but assuming he feels fine on Saturday, he'll throw another side session on Monday.
The news was not as good for young left-hander Macay McBride, who went onto the disabled list after pitching one inning in his first start of the season for Triple-A Toledo.
An examination by specialist Dr. David Altchek in New York on Thursday revealed a ligament tear in McBride's left elbow, according to a report in the Toledo Blade. He reportedly will undergo Tommy John ligament replacement surgery next week and miss the remainder of the season.
