Perez was optioned to Triple-A Salt Lake following Tuesday's game, Pedro Moura of the Los Angeles Times reports.
With Geovany Soto (knee) ready to come off the DL, Perez will head back to Triple-A to serve as organizational depth. That said, Soto has had a very hard time staying healthy this season, so it would not be surprising if Perez found his way back to the big leagues before the end of the season.
