The Story

The New York Yankees blanked the Boston Red Sox 4-0 at Fenway Park on April 21, 2026, completing a dominant road performance that left the DiamondIQ model's estimate of a Boston win falling from 33% before first pitch all the way to 0% by the final out. New York scattered its offense across three scoring innings, plating single runs in the second and eighth while breaking the game open with a two-run sixth, holding Boston to just four hits throughout.

The decisive moment came in the top of the sixth when Giancarlo Stanton doubled off Connelly Early, a swing that shifted win probability by plus 16.3 percentage points in New York's favor and stood as the single most impactful play of the game. Stanton finished as the top batter by the DiamondIQ model's estimate with a cumulative WPA of plus 17.6% and a RE24 of plus 1.8, numbers that reflected how thoroughly his contributions shaped the outcome. Marcelo Mayer added plus 6.8% WPA and Aaron Judge contributed plus 4.9% WPA as the Yankees spread their offensive value across the lineup. On the Boston side, a Caleb Durbin groundout into a double play in the bottom of the fifth cost the Red Sox 10.4 percentage points of win probability off Early's start, and an Andruw Monasterio flyout in the seventh gave back another 7.4 points, illustrating how Boston repeatedly stalled before it could generate any real threat.

Luis Gil led all pitchers with a WPA of plus 16.7%, anchoring the shutout effort and limiting Boston's most dangerous moments, including inducing that pivotal fifth-inning double play. Brent Headrick followed with plus 9.4% WPA, retiring Boston in order through the seventh despite Ceddanne Rafaela drawing a walk that briefly nudged Boston's chances upward by 6.1 percentage points. Tim Hill closed out the eighth with plus 4.9% WPA to preserve the clean sheet. New York's pitching staff allowed nothing to materialize from Boston's four hits, and the Yankees left Fenway having outperformed the pre-game probability lines by a substantial margin.
