Brown (shoulder) will make his next start at Triple-A Sugar Land on Wednesday, Brian McTaggart of MLB.com reports.
Manager Joe Espada said Friday that the Astros were debating whether to have Brown make another start in the minors, and they've officially decided to keep the right-hander in Triple-A for one more tuneup outing before activating him. Starting Wednesday would line him up to return from the 60-day IL on June 15 to face the Tigers at home.
