Puerto Rico defeated the Boston Red Sox 5-3 at JetBlue Park on March 3, 2026, handing the home side a loss that the DiamondIQ model's estimate made look increasingly inevitable as the game progressed. Boston entered with a 54% pre-game win probability, but that figure collapsed to 0% by the final out, reflecting a second half in which Puerto Rico's pitching and situational execution systematically dismantled any Red Sox comeback attempt.
The decisive swing in momentum came in the bottom of the seventh, where Nathan Hickey grounded into a double play off Luis Quiñones, a play that shifted win probability by -26.7% against Boston. That single sequence was the largest probability swing of the game, and Quiñones finished as the top pitching performer by WPA at +26.7%. Yophery Rodriguez countered with the most impactful offensive play for Puerto Rico, drawing a walk off Rico Garcia in the same inning for a +17.8% swing, and he led all batters with a +19.4% WPA and +1.3 RE24 on the day. The eighth inning brought another damaging moment for Boston, as Andruw Monasterio grounded into a double play off Yacksel Ríos for a -23.3% swing, effectively sealing the outcome. Ríos finished with a +16.0% WPA, and Elmer Rodríguez contributed +24.5% WPA to anchor Puerto Rico's pitching effort.
Beyond the battery, Max Ferguson added +14.2% WPA and Emmanuel Rivera contributed +11.6% WPA to support the Puerto Rico offensive effort, which produced nine hits with no errors against Boston's six hits and one error. The line score told a straightforward story: Puerto Rico struck for three runs in the first inning, added one in the third, then closed the game with runs in the sixth and seventh while Boston's late attempts came too little and too late against a Puerto Rico pitching staff that controlled leverage situations throughout.
