Scrubb (shoulder) was reinstated from the 60-day injured list and optioned to Triple-A Sugar Land on Wednesday, Chandler Rome of the Houston Chronicle reports.
Scrubb began a rehab assignment at the end of August and recorded a 1.69 ERA and 1.31 WHIP in 5.1 innings across 5.1 innings. He'll remain in the minors now that he's healthy but will be considered for a call-up if the Astros need a fresh bullpen arm late in the season.
