The Padres optioned Brito to Triple-A El Paso on Sunday.
Two days after being called up from El Paso, Brito will return to the minors. Since Brito was needed to cover 2.1 innings out of the bullpen in Saturday's 9-8 win and was unlikely to be available for the next couple of games, the Padres will swap him out of the bullpen for a fresh arm in right-hander Sean Reynolds, who was recalled from Triple-A in a corresponding move.
