Lorenzen (shoulder) threw 45 pitches over three innings during a simulated game Tuesday and will next report to Triple-A Salt Lake to begin a rehab assignment, Rhett Bollinger of MLB.com reports.
The right-hander progressed to throwing bullpen sessions last week and has now been cleared for game action in the minors. Lorenzen is eligible to be activated from the 60-day IL in early September and is expected to make two rehab starts before rejoining the big-league rotation.
