Angels manager Ron Washington said Tuesday that Stephenson (shoulder) threw a live bullpen session and is close to a rehab assignment, Rhett Bollinger of MLB.com reports.
Stephenson started the season on the 15-day IL after missing all of spring training due to right shoulder soreness. His live BP session is another step in the right direction as the right-hander continues to ramp up his activity. Stephenson appears poised to make his first rehab assignment in the next few days.
