Lorenzen (shoulder) is set to open the season on the disabled list, John Fay of The Cincinnati Enquirer reports.
Lorenzen hasn't resumed throwing since being shut down Monday with a right shoulder strain and the Reds won't rush him back to action with Opening Day creeping closer. The right-hander had been competing for a starting spot in spring training, but once he's healthy, Lorenzen will likely head back to the bullpen, where he'll fill a key setup role in front of closer Raisel Iglesias.
