Pittsburgh Pirates at Washington Nationals: Final Score & Recap

The Washington Nationals defeated the Pittsburgh Pirates 9-5 on July 3, 2026, at Nationals Park, a result that the DiamondIQ model's estimate saw coming into sharp focus early. Washington entered with a 56% pre-game home win probability, and by the final out that figure had climbed to 100%, with the decisive damage done in the third inning when the Nationals turned a competitive game into a commanding lead.

The third inning was the turning point, defined by a sequence of blows off Pirates starter Mitch Keller that collectively swung the game. Daylen Lile opened the scoring in the second with a home run off Keller, a swing worth plus 7.0% in win probability. The Pirates responded in the top of the third when Bryan Reynolds connected for a home run off Foster Griffin, adding plus 9.5% from Pittsburgh's perspective, but Washington answered emphatically in the bottom half. Lile doubled for plus 6.1%, James Wood followed with a triple worth plus 8.2%, and José Tena capped the inning with a home run for the single largest win-probability swing of the game at plus 11.4%, all three off Keller. The Nationals added two runs in both the seventh and eighth innings to build an insurmountable cushion before Pittsburgh mounted a four-run ninth that proved cosmetic.

Lile finished as the game's top performer by the DiamondIQ model's measure, posting plus 12.8% in win probability added alongside plus 3.3 in RE24, with his second-inning home run and third-inning double serving as the foundation of Washington's offensive output. Tena contributed plus 10.6% and Wood plus 8.4% as supporting pillars of that pivotal third. On the pitching side, Griffin led Washington's staff at plus 7.0% despite surrendering the Reynolds home run, followed by Clayton Beeter at plus 5.9% and Orlando Ribalta at plus 3.3%, a collective effort that held Pittsburgh in check across the middle innings and protected the Nationals' advantage.
