Alexander (shoulder) progressed to Triple-A Oklahoma City to continue his rehab assignment Thursday, Alex Freedman of Oklahoma City's broadcast team reports.
Alexander began a rehab assignment on June 18 with Low-A Rancho Cucamonga. That stint appears to have gone as planned, and he's now expected to throw at some point in Oklahoma City's game Thursday. Alexander is eligible to return from the injured list in early July and appears on track for activation close to that time.
