Miami Marlins at Cincinnati Reds: Final Score & Recap

The Miami Marlins handed the Cincinnati Reds an 8-4 defeat at Great American Ball Park on August 15, 2026, with the DiamondIQ model's estimate of a Cincinnati victory dropping from a pre-game 52 percent all the way to zero by the final out. The game remained relatively tight through the middle innings, with Cincinnati showing signs of life in the third and fifth frames before Miami's eighth-inning outburst ultimately settled the matter. Ryan Gusto absorbed the heaviest damage for the Reds, surrendering Ke'Bryan Hayes's home run in the fifth inning, which shifted win probability by 13.1 percent, followed almost immediately by Matt McLain's home run off the same pitcher for an additional 12.4 percent swing. Sal Stewart had offered Cincinnati a brief boost in the third with a single that moved the needle 18.1 percent in the home team's favor, but those gains were systematically erased as Miami's offense found its rhythm late.

The decisive moment arrived in the top of the eighth, when Miami erupted for four runs to push the lead beyond reach. Heriberto Hernández delivered the single most impactful blow of the night, a single off Sam Moll that registered a 26.4 percent win-probability swing, while Esteury Ruiz reaching on a hit by pitch against Tejay Antone added another 12.0 percent shift in the Marlins' favor during that same frame. When measuring individual contributions across the full game, McLain led all batters with a 26.3 percent WPA and a RE24 of plus-2.0, while Jakob Marsee posted the best run-environment figure at plus-2.2 to go with a 22.0 percent WPA. Hernández finished close behind at plus-23.3 percent WPA. On the pitching side, Miami's late relievers locked things down, with Calvin Faucher leading the staff at plus-8.9 percent WPA, followed by Luis Mey at plus-8.5 percent.
