Pittsburgh Pirates at Cincinnati Reds: Final Score & Recap

The Pittsburgh Pirates opened the 2026 season with a commanding 8-3 victory over the Cincinnati Reds at Great American Ball Park on March 31, erasing what the DiamondIQ model's estimate had been a 54 percent pre-game home win probability for Cincinnati and leaving it at zero by the final out. The Pirates did the bulk of their damage in the second inning, plating five runs in a sequence that effectively decided the contest before it had a chance to develop into anything competitive.

The decisive blow of the game came from Ryan O'Hearn, whose second-inning home run off Brandon Williamson carried a win-probability swing of plus 11.9 percent and represented the single most impactful play of the afternoon. Cincinnati had two opportunities to claw back into the game but squandered both. Will Benson's pop out in the bottom of the second off Bubba Chandler cost the Reds 11.6 percent in win probability, and TJ Friedl grounded into a double play in the third, shedding another 8.4 percent. A Nathaniel Lowe double play in the eighth off Dennis Santana eliminated any remaining hope, costing Cincinnati 9.5 percent in win probability.

Among individual performers, O'Hearn led all batters with a WPA of plus 11.6 percent and a RE24 of plus 2.8, while Oneil Cruz added plus 9.6 percent WPA and led position players with a RE24 of plus 3.2. Marcell Ozuna contributed plus 9.9 percent WPA despite a negative RE24 of minus 0.7, benefiting from favorable sequencing around his at-bats. On the mound, Dennis Santana paced the pitching staff with plus 11.8 percent WPA, followed closely by Yohan Ramirez at plus 11.1 percent and Bubba Chandler at plus 8.3 percent, as Pittsburgh's bullpen held Cincinnati's offense largely in check after the Reds scratched across a run in the third. The DiamondIQ model leans toward crediting the second-inning offensive eruption as the structural turning point of a game that was rarely in doubt.
