Boston Red Sox at Pittsburgh Pirates: Final Score & Recap

The Pittsburgh Pirates defeated the Boston Red Sox 8-4 at PNC Park on August 14, 2026, turning what opened as a virtual coin flip into a comfortable home victory. The DiamondIQ model's estimate entered the game with Pittsburgh holding a 49% win probability, but by the final out that figure had climbed to 100%, reflecting how thoroughly the Pirates controlled the contest once they established their early lead.

The game's decisive sequence unfolded across the second and fourth innings, built largely on the shoulders of Rafael Flores Jr. against Boston starter Jake Bennett. Flores Jr. got Pittsburgh on the board with a home run in the second that added 7.8% to Pittsburgh's win probability, then returned in the fourth with a single worth another 6.9% as the Pirates sent three runs across in that frame, with Bryan Reynolds contributing a key double registering plus-8.8% during that same fourth-inning rally. The Pirates then absorbed a two-run Boston response in the top of the fifth, only for Brandon Lowe to answer immediately with a home run off Jovani Morán that swung the win probability 16.4% back toward Pittsburgh and functioned as the single largest leverage moment of the game, effectively sealing the outcome.

Flores Jr. finished as the game's top offensive contributor with a combined WPA of plus-14.5% and an RE24 of plus-2.5, while Lowe was right behind at plus-14.2% WPA and plus-2.1 RE24 despite his damage being concentrated in one decisive swing. Reynolds added plus-9.1% WPA to round out a balanced Pittsburgh offensive effort. On the mound, Bubba Chandler led Pittsburgh's pitching staff with a plus-6.4% WPA contribution, supported by Gregory Soto at plus-2.0%, as the Pirates held Boston to four runs on nine hits despite committing one error of their own.
