Athletics at Houston Astros: Final Score & Recap

The Houston Astros shut out the Athletics 4-0 on August 21, 2026, at Daikin Park, improving the DiamondIQ model's pre-game home win probability estimate from 66 percent to a final 100 percent as Houston's pitching staff allowed just three hits across nine innings. The Astros built their lead methodically, scoring once in the fourth, twice in the fifth, and once more in the seventh, never allowing Oakland a foothold in the game.

The decisive stretch came in the fourth and fifth innings, where J.T. Ginn absorbed the bulk of the damage. Daulton Varsho's double in the bottom of the fourth added 10.7 percent to Houston's win probability, and Yordan Alvarez followed with the game's single biggest positive swing the following inning, his double carrying a 12.4 percent win-probability boost. Isaac Paredes contributed further in that same fifth frame with a double worth 7.3 percent. Ginn had actually received a measure of relief earlier when Raynel Delgado hit into a strikeout double play in the second inning, a play that swung 7.8 percent against the Astros, but Oakland was unable to convert any of its three hits into runs. Max Muncy's strikeout against Bryan Abreu in the seventh, dropping Athletics' win probability by 6.1 percent, effectively closed the door on any late threat.

Hayden Wesneski led all pitchers with a 14.3 percent win-probability contribution, and Bryan Abreu and Bennett Sousa each added 5.0 percent in relief. Among position players, Alvarez finished as the top performer with a 14.2 percent WPA and a RE24 of plus-2.3, while Donovan Walton posted 9.5 percent WPA and Paredes contributed 8.5 percent. The DiamondIQ model leans toward Houston's pitching depth as the primary driver of the outcome, with Wesneski and his bullpen support neutralizing an Athletics lineup that generated no meaningful run-scoring opportunities.
