The Chicago Cubs (76-57) and Arizona Diamondbacks (70-63) conclude their three-game series at Chase Field with the D-backs holding a 2-1 edge after a 5-4 walk-off win on August 25 and a 2-0 shutout on August 26. Eduardo Rodriguez (13-4, 2.61 ERA) has anchored Arizona's rotation while the Cubs' Matthew Boyd (8-2, 4.15 ERA) has shown inconsistency. Both clubs remain firmly in the NL playoff picture—the Cubs sit second in the Central and the D-backs trail the Padres by one game for the final wild-card spot—making late-season roster health and bullpen reliability central to outcomes. Multiple Arizona starters, including Zac Gallen and Corbin Burnes, remain on the injured list, while Chicago's recent road form has included both high-scoring outbursts and shutout losses. Extreme Phoenix heat and the D-backs' home advantage add situational weight heading into the final month.
