The Houston Astros and Washington Nationals played to a 4-4 tie on February 27, 2026, at CACTI Park of the Palm Beaches, with neither club able to break the deadlock through nine innings. Washington had built its entire lead in the third inning, when Luis García Jr. connected on a home run off Spencer Arrighetti that swung win probability by 23.3 percentage points in the Nationals' favor according to the DiamondIQ model's estimate. A Dylan Crews single in the same frame, also against Arrighetti, added another 9.7 percentage points to Washington's advantage, putting Houston in a significant early hole.
The Astros answered with a sustained rally beginning in the fourth inning. Taylor Trammell's double off Holden Powell shifted win probability 13.7 points toward Houston, and the visitors added two more runs in the fifth when Jax Biggers singled off Connor Van Scoyoc for an 18.7-point swing, the second-largest single play of the game. Those back-to-back two-run innings erased Washington's lead entirely and left the game level heading into the middle frames. The DiamondIQ model had opened with a 54 percent pre-game win probability favoring the Nationals, but the final figure registered at zero percent given the tie result.
Individually, Luis García Jr. led all position players with a combined WPA of plus-25.9 and a RE24 of plus-3.2, while Jax Biggers followed at plus-24.3 WPA and plus-2.3 RE24 to pace his club. On the mound, Shinnosuke Ogasawara was the most impactful arm of the afternoon at plus-24.1 WPA, with Sam Carlson contributing plus-13.3. Washington's best scoring opportunity in the late innings evaporated in the seventh when Sergio Alcántara struck out against Hudson Leach, a moment that swung win probability 11.6 points away from the Nationals and preserved the deadlock through the final out.
