Atlanta Braves at Washington Nationals: Final Score & Recap

The Atlanta Braves defeated the Washington Nationals 8-5 at Nationals Park on September 23, 2023, with the DiamondIQ model's estimate entering the game giving Washington a 34 percent chance of winning at home — a figure that had collapsed to zero by the final out. Atlanta broke the game open in the fourth inning, when Kevin Pillar delivered the single most impactful offensive play of the night, a home run off Joan Adon that shifted win probability 20.6 percentage points in the Braves' favor. That same frame saw Orlando Arcia add a double off Adon worth another 12.7 percentage points, and Arcia returned in the seventh with a run-scoring single off Cory Abbott that swung the model another 15.3 points Atlanta's way. Washington had briefly created separation in the third, when Keibert Ruiz doubled off Spencer Strider to generate an 18.3-point swing for the Nationals, but Atlanta's fourth-inning eruption of four runs erased that lead entirely before Washington could build on it. Forrest Wall sealed the outcome with a home run off José A. Ferrer in the sixth, a swing worth 20.3 percentage points that effectively ended any realistic path to a Nationals comeback.

Arcia and Wall finished as the game's co-leaders by win-probability added, each posting a figure of plus-24.5 percent with RE24 marks of plus-2.0 and plus-1.9 respectively, making them the clearest drivers of the Braves' offensive output. Ruiz led Washington's contributors at plus-20.0 percent WPA and plus-1.7 RE24, though his third-inning production proved insufficient against Atlanta's sustained offensive pressure. In relief, Jordan Weems led Braves pitchers with a plus-4.7 percent WPA, followed by Joe Jiménez at plus-3.6 and Jesse Chavez at plus-3.5, a trio that collectively held the Nationals at bay through the game's final innings and preserved the three-run margin.
