Stephenson (shoulder) will be required to throw another live batting practice session Sunday before taking the next step of getting into a game, Mark Sheldon of MLB.com reports.
Stephenson had a previous batting practice session Thursday, but he's definitely behind schedule in his attempt to be ready for Opening Day. Because Stephenson is out of options, it's likely that the Reds will begin the season by putting him on the IL and having him go on a rehab assignment at Triple-A Louisville.
