Ryu (shoulder) threw a 30-pitch bullpen session Tuesday, J.P. Hoornstra of the Southern California News Group reports.
A groin strain temporarily interrupted Ryu's recovery from shoulder surgery, but he's back on elevated ground and a return to live sessions may not be too far off. Still, the setback does put a May return to the majors in question. Ryu's timetable should start to take shape once he ramps up closer to a rehab assignment.
