Flores is not in the lineup Wednesday against the Diamondbacks, Amy Gutierrez of the Giants' official site reports.
Flores rejoined the lineup Tuesday after sitting out a couple games with back soreness, and he'll return to the bench Wednesday. The 29-year-old has an .871 OPS with five homers, nine RBI and 10 runs in 18 games since the All-Star break. However, his playing time could take a slight dip with Tommy La Stella (hamstring) making his return from the 60-day injured list.
