The Houston Astros defeated the Washington Nationals 7-1 on March 6, 2026, at CACTI Park of the Palm Beaches, turning what opened as a relatively balanced contest into a decisive home victory. The DiamondIQ model's estimate entered the day with Houston holding a 54% win probability and closed at 100%, a reflection of how thoroughly the Astros controlled the game's late innings after a scoreless first five frames.
The pivotal stretch came in the sixth and seventh innings, where Houston built its margin through a sequence of high-leverage moments. Joey Loperfido's single in the bottom of the sixth off Julian Fernández shifted win probability by 9.1 percentage points, and a hit by pitch to Jax Biggers off Zach Penrod added another 7.9 points as the Astros extended their advantage. John Garcia then punctuated the seventh with a home run off Bryce Montes de Oca, the single largest win-probability swing of the game at plus 9.8 points. Washington's lone meaningful offensive moment came in the top of the seventh, when Daylen Lile connected for a home run off Kai-Wei Teng for a plus 9.6-point swing, but by that point the deficit was too large to overcome. An earlier César Salazar sacrifice bunt in the bottom of the third off Cade Cavalli also registered as a consequential play at plus 9.4 points, helping Houston establish early run-scoring position.
Jax Biggers led all position players with a plus 13.9% WPA and plus 1.8 RE24, finishing as the game's most impactful offensive contributor by the DiamondIQ model's estimate. Garcia followed at plus 9.8% WPA and Loperfido at plus 5.9%. On the mound, Mike Burrows paced Houston's pitching staff with plus 8.8% WPA, followed by Bennett Sousa at plus 6.4% and Cavalli at plus 5.5%. Washington's error-prone defense, committing three miscues against none for Houston, compounded the offensive struggles as the Nationals managed only two hits on the afternoon.
