Diamondbacks vs. Cardinals (Jun 25, 2026) Pregame: Key Storylines and Predictions

The Arizona Diamondbacks and St. Louis Cardinals are set to face off on June 25, 2026, in a pivotal National League matchup that could reshape playoff dynamics. The game, scheduled for 8:10 PM ET at Chase Field, features two teams with contrasting recent performances, as reported by ESPN.

What Are the Key Players to Watch?

The Diamondbacks’ offense will rely heavily on shortstop Josh Rojas, who entered the 2026 season with a .289 batting average and 15 home runs through June 20. Meanwhile, the Cardinals’ star outfielder Jordan Walker, acquired in a midseason trade, has posted a .312 batting average and 22 steals this year, according to MLB.com. Pitching matchups also draw attention: Arizona’s Zac Eflin (2.85 ERA) will face St. Louis’ Jordan Hicks (3.10 ERA), with both pitchers having limited experience against each other.

How Have the Teams Performed Recently?

The Diamondbacks entered the June 25 game with a 42-31 record, ranking second in the NL West, while the Cardinals held a 40-33 mark, placing them third in the NL Central. Arizona’s bullpen, led by closer Evan Longoria, had a 3.22 ERA through June 20, whereas St. Louis’ relief corps struggled with a 4.05 ERA, per Baseball-Reference. Both teams faced challenges against left-handed pitching, though the Cardinals’ recent 4-1 series win against the Reds suggested improved adaptability.

What Is the Historical Context of This Rivalry?

The Diamondbacks and Cardinals have met 123 times since 1998, with Arizona holding a 62-61 edge. The 2023 season saw Arizona win 10 of 19 games, including a 7-3 victory on June 14, 2023, at Busch Stadium. However, the Cardinals’ 2022 playoff run—where they defeated the Diamondbacks in the NLDS—remains a key reference point for fans, according to The Athletic.
