Brown (shoulder) has been reinstated from the 60-day IL on Tuesday.
After completing four rehab assignments and building up to 78 pitches in one start, Brown is back with the big-league club for the first time since being placed on the injured list April 5. Prior to that, the 27-year-old had made just two starts, during which he racked up 17 strikeouts. Houston will get a much-needed addition and boost to its starting rotation, which has been marred by injuries all season long. Collin Price was optioned to Triple-A in order to make room for Brown on the active roster. Brown will be Tuesday's starter against Detroit.
