Los Angeles Angels at Boston Red Sox: Final Score & Recap

The Los Angeles Angels handed the Boston Red Sox a decisive 6-1 defeat at Fenway Park on September 8, 2026, erasing what the DiamondIQ model had estimated as a 70 percent pre-game win probability for the home side. Los Angeles built its lead methodically, scoring in the second, third, fifth, and ninth innings while holding Boston to a single run in the seventh. The Angels finished with 15 hits and committed no errors, while the Red Sox managed just four hits across the entire game.

The pivotal early exchange set the tone for the afternoon. In the bottom of the second, Eli White grounded into a forceout off Reid Detmers that cost Boston 9.4 percent in win probability, a swing that reflected how thoroughly Detmers was neutralizing Red Sox threats. Jose Siri answered in the top of the third with a single off Patrick Sandoval that added 9.1 percent to the Angels' win probability, and Siri finished among the game's top performers by WPA at plus-7.7 percent. The seventh inning offered Boston its best glimpse of life, with Caleb Durbin drawing a walk off Jose Fermin for a plus-8.7 percent swing and Nick Sogard adding a single worth plus-8.0 percent, but Andruw Monasterio's strikeout to end the threat cost the Red Sox 7.8 percent and effectively closed the door.

Reid Detmers was the game's dominant force, leading all pitchers with a plus-35.9 percent WPA contribution as he suppressed Boston's lineup throughout. Vaughn Grissom led all position players at plus-14.6 percent WPA and a plus-1.3 RE24, providing the offensive backbone alongside Durbin's plus-8.5 percent WPA effort. Tayler Saucedo and Ryan Watson provided clean relief work at plus-3.5 and plus-1.7 percent WPA respectively, completing a thoroughly dominant performance from the Los Angeles pitching staff.
