Flores (hamstring) is out of the lineup for Sunday's game against the Mets.
Flores will be relegated to the bench for a second straight game after his left hamstring tightened up on him Friday. According to MLB.com, he's considered day-to-day, and the Giants don't believe he'll require a trip to the injured list. With Flores sitting out Sunday, Rafael Devers will serve as the designated hitter while Dominic Smith steps in at first base.
