Lorenzen is preparing to return to the Reds as a reliever, the Cincinnati Enquirer's C. Trent Rosecrans reports.
He is still working in extended spring training before heading out on a rehab assignment. This was certainly expected, given Lorenzen's struggles as a starter. With most pitchers this can be the kiss of death for their fantasy potential, but Lorenzen has two plus pitches and Reds have the worst bullpen in baseball, so he could find his way to saves before the end of the season if the transition goes off without a hitch.
