Bell will start at first base and bat cleanup in Sunday's game against the Astros.
Bell was on the bench for the first two games of the series, but he'll move back into the starting nine for the finale while Ketel Marte and Christian Walker get the evening off. Though Marte should eventually reclaim a full-time role at second base after being eased back in the lineup at designated hitter in the previous two contests, Arizona likely won't have room in the lineup for Bell against right-handed pitching while Walker and Joc Pederson occupy first base and the DH spot, respectively. Bell should at least replace the lefty-hitting Pederson in the lineup when the Diamondbacks face left-handed pitching.
