The Padres optioned Brito to Triple-A El Paso on Saturday.
Brito joined the active roster Tuesday after spending the first few months of the season on the injured list, but he'll now be pushed back to Triple-A in order to make room for Matt Waldron's (forearm) return from the IL. Brito conceded two earned runs in 4.1 innings during his two appearances with the big club, and he could be an option to return to San Diego later in the season to provide length out of the bullpen.
