Grichuk is out of the lineup for Sunday's game against the Astros.
Grichuk started in left field in each of the last three games, with the Diamondbacks facing left-handed starting pitchers on all occasions. He's been on the bench, however, for each of the Diamondbacks' three matchups with right-handed pitchers since Lourdes Gurriel (calf) landed on the injured list Tuesday. Grichuk looks as though he'll be ticketed for the short side of a platoon in left field with Pavin Smith until Gurriel returns from the IL.
