Los Angeles Angels at Houston Astros: Final Score & Recap

The Los Angeles Angels battered the Houston Astros 18-3 at Daikin Park on August 20, 2026, in a rout that erased a pre-game home win probability of 64 percent according to the DiamondIQ model's estimate, which finished at zero. Los Angeles collected 18 hits and scored in five of nine innings, doing most of its damage in a six-run fourth and a four-run fifth that put the game well beyond reach. Houston committed two errors and its pitching staff was unable to contain an Angels lineup that sent multiple runners around in the middle innings, with Bryan King and Peter Lambert both absorbing significant damage after starter Grayson Rodriguez was lifted.

The decisive stretch began in the fourth inning, where a Moisés Ballesteros single off Bryan King added 7.8 percentage points of win probability and represented the single biggest positive swing of the night for Los Angeles. Zach Neto followed with a single off Peter Lambert worth another 6.0 percentage points, extending what became a six-run frame that functionally ended the contest. Grayson Rodriguez had kept Houston's deficit from being even steeper in the early going, with a LaMonte Wade Jr. strikeout in the second inning that swung win probability by 9.3 points in Houston's favor and a Christian Vázquez double play that erased 6.0 additional points from the Angels' ledger, though Yordan Alvarez's double in the third added back 6.7 points for the home side.

Ballesteros led all position players with a WPA of plus-14.3 and an RE24 of plus-1.3, while Adam Frazier contributed plus-9.7 WPA and plus-1.1 RE24 in what was a broad offensive effort across the Angels lineup. Alvarez paced Houston's batters with plus-8.0 WPA and plus-1.2 RE24, but those contributions amounted to little in a 15-run loss. Grayson Rodriguez was the game's most impactful pitcher by WPA at plus-15.6, a figure reflecting his early effectiveness before the Angels offense overwhelmed the Houston bullpen in the middle innings.
