Morrow (shoulder) threw three sets of 15 pitches in a simulated game Saturday, Dennis Lin of the Union-Tribune reports. Morrow has progressed to throwing simulated games after tossing a pair of bullpen sessions over the last week. There's still no definitive timetable for Morrow to return, but if he continues to progress without setbacks he should set out on a rehab assignment in the not-so-distant future.
