The rivalry carried into the 2026 season, where the two teams met again in a summer series in Cincinnati. On June 14, 2026, catcher Gabriel Moreno delivered a decisive eighth-inning home run to send the Diamondbacks past the Reds 5-3, a result that marked manager Torey Lovullo's 700th career win. Zac Gallen again drew the start for Arizona, while Cincinnati right fielder Noelvi Marte narrowly missed robbing Moreno's game-changing blast at the wall. The outcome underscored Arizona's edge in recent close contests between the sides. [Bozeman Daily Chronicle, Jun 14]
