The Atlanta Braves routed the Boston Red Sox 15-8 at CoolToday Park on February 27, 2026, in a game that was effectively decided by a massive third-inning rally. The DiamondIQ model opened with Atlanta holding a 54 percent pre-game win probability, and by the time the dust settled that figure had reached 100 percent.
Boston briefly seized momentum in the top of the third when Ceddanne Rafaela connected on a home run off Chris Sale, a swing that shifted win probability by plus-18.4 percent in the Red Sox's favor and represented their most impactful offensive moment of the afternoon. Atlanta answered immediately and emphatically in the bottom half, scoring 11 runs in the inning to flip the game entirely. Mike Yastrzemski ignited the damage with a single off P.J. Labriola that added 17.7 percent to Atlanta's win probability, and Ozzie Albies followed with a double worth 12.9 percent. Michael Harris II contributed a single worth an additional 7.1 percent in the same frame. Yastrzemski had already done damage in the second inning with a home run off Brayan Bello, a plus-7.4 percent swing that gave Atlanta an early lead before the third-inning explosion made the outcome a formality.
Yastrzemski finished as the game's dominant performer, accumulating a plus-25.1 percent WPA and a plus-3.9 RE24 across his multi-hit effort. Rafaela led Boston with a plus-18.4 percent WPA on the strength of his third-inning blast, though the Red Sox's pitching staff could not contain the damage. Albies finished at plus-11.4 percent WPA for Atlanta, while Darius Vines led the Braves pitching staff with a plus-1.0 percent WPA contribution. Boston added three runs in the seventh to close the gap cosmetically, but Atlanta's 15-run output on 13 hits and no errors was more than sufficient.
