Reynolds was sent down to Triple-A Las Vegas on Saturday, Mike Puma of the New York Post reports.
Reynolds was optioned in order to provide a spot for Steven Matz, who will be pitching the second game of Saturday's doubleheader. Since being called up in late April, Reynolds has gone 4-for-22 with one home run and one RBI with three walks and nine strikeouts with the Mets. The 26-year-old will get more chances at the Triple-A level.
