Meckler was optioned to Triple-A Sacramento on Wednesday.
Analysis: Meckler kept his roster spot over Luis Matos after Mike Yastrzemski returned from the injured list last week, but the Giants are swapping out the two players now. The 23-year-old posted a .578 OPS during his first 20 games in the big leagues.
Wade Meckler On bench against lefty
Meckler is out of the lineup for Sunday's game against Atlanta, Alex Pavlovic of NBC Sports Bay Area reports.
Analysis: Meckler will join fellow left-handed hitters Joc Pederson and LaMonte Wade on the bench while Atlanta brings a southpaw (Jared Shuster) to the hill for the second straight game. Austin Slater will replace Meckler in center field and will bat leadoff.
