Barnes was optioned to Triple-A Oklahoma City on Sunday, Ken Gurnick of MLB.com reports.
Barnes had been acting as a utility player and emergency third catcher during his latest stint with the big club, but with the versatile Enrique Hernandez (ribs) cleared to return from the DL, there was no need for the Dodgers to keep both players on the 25-man roster. The 26-year-old Barnes was with the Dodgers for just over a week, recording one hit across four at-bats.
