One week after promoting Scott McGough to Triple-A New Orleans, the Marlins have sent him back down to the same team, per the Miami Herald.
The move was necissatated by the reinstatement of fellow right-handed reliever Andre Rienzo from the disabled list.
McGough pitched scoreless ball in two of his three appearances, but allowed three runs on five hits in two-thirds of an inning in the other.
Rienzo had been down for just over three weeks with a left knee laceration.
