Boston Red Sox at Baltimore Orioles: Final Score & Recap

Baltimore held Boston scoreless through six innings before erupting for two runs in the seventh and three more in the eighth to take a 5-2 final at Oriole Park at Camden Yards on September 30, 2023. The Orioles entered with a 68 percent pre-game win probability according to the DiamondIQ model, and that figure reached 100 percent by the final out, a journey driven almost entirely by a pair of late-inning bursts against Red Sox relievers. Boston out-hit Baltimore 14 to 7 but left runners stranded across the afternoon, and a first-error night for the Orioles underscored how cleanly Baltimore executed when it mattered most.

The decisive sequence began in the bottom of the seventh, when Heston Kjerstad singled off Josh Winckowski to swing win probability 14.6 percent in Baltimore's favor, the single largest play of the game by that measure. Ryan Mountcastle followed with a double off the same pitcher, adding another 14.1 percent shift and putting the Orioles on the board with a two-run frame. Boston briefly answered in the eighth with Trevor Story's run-scoring single off Jack Flaherty, a swing of plus 12.3 percent, but Ceddanne Rafaela's strikeout to end a threat cost the Red Sox 10.8 percent in win probability and snuffed the rally. An earlier Alex Verdugo double-play grounder in the third off Kyle Gibson, a negative 8.0 percent play, had similarly deflated Boston opportunities before they could develop.

On the individual ledger, Kjerstad finished as the top position player by WPA at plus 14.6 percent with a RE24 of plus 1.1, while Mountcastle posted plus 10.0 percent WPA and Jorge Mateo added plus 7.8 percent to round out Baltimore's most impactful bats. On the mound, Kutter Crawford was the standout of the evening with an extraordinary plus 38.1 percent WPA, the highest single-pitcher figure in the game, supported by Bruce Zimmermann at plus 15.4 percent and starter Kyle Gibson at plus 13.1 percent. Baltimore's pitching staff combined to neutralize Boston's considerable hit total and deliver a clean, error-free performance that the DiamondIQ model ultimately assessed as an inevitable outcome well before the final pitch.
