Boston Red Sox at Baltimore Orioles: Final Score & Recap

The Boston Red Sox completed a 3-0 shutout of the Baltimore Orioles at Oriole Park at Camden Yards on September 29, 2023, overcoming a pregame DiamondIQ model estimate that gave Baltimore a 68 percent chance of winning at home. Boston scattered three runs across the fifth and ninth innings against a Baltimore side that managed just three hits and committed one error, never threatening seriously enough to put the model's opening probability to use.

The decisive moment came in the top of the fifth inning, when Trevor Story connected on a home run off John Means that swung win probability by 19.3 percent in Boston's favor. That single swing was the central axis of the game, and Story finished as the top offensive performer with a cumulative WPA of plus-23.2 percent and an RE24 of plus-1.3, matching Justin Turner, who added plus-5.8 percent WPA and plus-1.3 RE24 of his own. Baltimore's best chance to respond came in the bottom of the fifth when Jordan Westburg doubled off Nick Pivetta for a plus-5.4 percent swing, but the Orioles were unable to convert that opportunity into a run. Jorge Mateo's ground into a double play in the third inning had already cost Baltimore minus-7.9 percent in win probability, and by the time Garrett Whitlock retired Ryan O'Hearn on a strikeout in the ninth for a plus-5.4 percent swing, the outcome was sealed.

Nick Pivetta was the game's dominant performer by any measure, posting a staggering plus-47.4 percent WPA while holding Baltimore in check through the bulk of the contest. Garrett Whitlock added plus-10.2 percent WPA in relief, and Jorge López contributed plus-7.7 percent to round out a Boston pitching staff that allowed no runs across nine innings on just three hits. The DiamondIQ model's estimate moved from Baltimore's pregame 68 percent probability all the way to zero, a complete reversal driven almost entirely by Story's fifth-inning blast and Pivetta's suffocating command of the Orioles lineup.
