Los Angeles Angels at Oakland Athletics: Final Score & Recap

The Oakland Athletics handed the Los Angeles Angels a lopsided 9-2 defeat on September 1, 2023, at Oakland Coliseum, turning what the DiamondIQ model had estimated as a 35% home win probability into a near-certainty before the game was even half over. The Athletics scored five runs in the bottom of the fourth inning in a sequence that effectively ended the contest, and Oakland's DiamondIQ model estimate climbed steadily to 100% by the final out. The Angels managed just two runs across the final two innings, far too little to threaten a comeback.

The fourth inning was the decisive turning point and produced the game's most impactful plays by win-probability swing. Aledmys Díaz opened the scoring with a double off Patrick Sandoval that shifted win probability by 11.9 percentage points in Oakland's favor, the single largest swing of the night. Jonah Bride followed with a single off Sandoval worth 7.1 percentage points, and Brent Rooker added a double off Sandoval for another 6.8-point swing. When Jimmy Herget entered, Zack Gelof greeted him with a double that moved the needle another 9.7 points. Earlier in the same inning, Logan O'Hoppe's grounded into double play had cost the Angels 6.1 percentage points and extinguished whatever small threat they had posed.

JP Sears was the game's standout performer by a wide margin, accumulating a WPA of plus-27.5% on the mound for Oakland and keeping the Angels' lineup largely in check throughout his start. Among position players, Brent Rooker led with a WPA of plus-9.9% to go with a RE24 of plus-0.5, while Jordan Diaz contributed a plus-9.6% WPA and the evening's best RE24 mark of plus-2.2, reflecting his sustained run-creation impact across multiple situations. Aledmys Díaz rounded out Oakland's top performers at plus-7.8% WPA as Oakland's 14 hits overwhelmed a Los Angeles pitching staff that had no answer for the Athletics' lineup through the game's most consequential frame.
