Baltimore Orioles at Washington Nationals: Final Score & Recap

The Washington Nationals defeated the Baltimore Orioles 13-3 at Nationals Park on May 16, 2026, a game that was never particularly close after the first pitch. The DiamondIQ model opened with a 60 percent pre-game win probability in favor of the home side and closed at 100 percent, a reflection of how thoroughly Washington controlled the contest from the second inning onward.

The decisive scoring began in the bottom of the second, when Keibert Ruiz connected on a home run off Chris Bassitt, a swing the DiamondIQ model credited with a +16.0 percent win-probability swing and the single largest play of the game. That blow set the tone as Washington built a 4-0 lead through the first three innings. The game's most chaotic stretch arrived in the seventh, when the two clubs combined for ten runs. Baltimore threatened in the top half, with Taylor Ward singling off PJ Poulin for a +10.9 percent swing and Tyler O'Neill following with a home run off Cade Cavalli worth +9.6 percent, a sequence that briefly tightened the model's outlook before Washington answered with authority. Brady House delivered a double off Keegan Akin in the bottom of the seventh that registered a +13.2 percent swing, anchoring a seven-run inning that put the game firmly out of reach.

Ruiz finished as the top performer by the DiamondIQ model's accounting, posting a combined +20.2 percent win-probability added and a +3.5 RE24, while Brady House contributed +13.2 percent WPA and +2.8 RE24. CJ Abrams rounded out the top three Washington contributors with +11.0 percent WPA. Baltimore's pitching staff absorbed the damage across the full game, and the final line of 13 runs on 13 hits with no errors for Washington reflected clean, efficient execution from a Nationals offense that dominated a Beltway rivalry matchup from wire to wire.
