The Houston Astros defeated the Miami Marlins 1-0 on March 15, 2026, at CACTI Park of the Palm Beaches, with the DiamondIQ model's estimate shifting from a 54 percent pre-game home win probability all the way to 100 percent by the final out.

The decisive sequence came in that eighth inning, where Shay Whitcomb's double off Bradley Blalock was the single most impactful play of the game, swinging the DiamondIQ model's estimate by plus 16.6 percent in Houston's favor. Mason Lytle followed with a flyout off Garrett Acton that nonetheless added another plus 7.8 percent to Houston's win probability, suggesting the run had already scored or was in the process of scoring with favorable base-out conditions. Miami mounted a brief threat in the top of the ninth when Abrahan Ramirez singled off AJ Blubaugh to push the Marlins' win probability up 7.6 percent, but Griffin Conine's strikeout cost Miami 8.9 percent and PJ Morlando's strikeout another 7.1 percent, effectively ending the rally and sealing the outcome.
