Diamondbacks catcher Gabriel Moreno nears return from oblique strain during the series, potentially strengthening their lineup after recent IL stints for Pavin Smith (elbow) and others. Cubs bullpen depth tested by Riley Martin (elbow) and Shelby Miller (UCL) on injured list, while both clubs wrap midweek series—D-backs at Brewers, Cubs at Padres—factoring rest and travel into matchup dynamics.",
