The Pittsburgh Pirates defeated the Tampa Bay Rays 5-1 at PNC Park on April 17, 2026, handing Tampa Bay a lopsided loss in a game that was never particularly close after the sixth inning. The DiamondIQ model opened with a 64 percent pre-game home win probability favoring Pittsburgh and finished at 100 percent, reflecting how thoroughly the Pirates controlled the contest. Pittsburgh out-hit Tampa Bay 11 to 5, and neither side committed an error in a clean but one-sided affair.
The decisive sequence came in the sixth inning, where the game's two most impactful plate appearances unfolded in opposite halves. Junior Caminero gave Tampa Bay a brief flicker of life in the top of the sixth with a single off Bubba Chandler that shifted win probability 13.8 percent in the Rays' favor, though Yandy Díaz's pop out against Chandler moments later erased much of that momentum with a 6.4 percent swing back toward Pittsburgh. The answer came swiftly in the bottom half, when Oneil Cruz launched a home run off Griffin Jax that produced the game's single largest win-probability swing at plus 24.7 percent. Pittsburgh added two more runs in the bottom of the eighth, punctuated by a Brandon Lowe double off Yoendrys Gómez that added 8.4 percent in win probability, though it came too late to matter for Tampa Bay.
Cruz finished as the game's top performer by WPA at plus 20.9 percent with an RE24 of plus 0.8, while Spencer Horwitz contributed a plus 12.1 percent WPA and led all players with a plus 1.6 RE24. On the mound, Nick Martinez led Pittsburgh's pitching staff with a plus 15.1 percent WPA, supported by Bubba Chandler at plus 9.1 percent and Gregory Soto at plus 8.1 percent. The DiamondIQ model leans toward crediting Cruz's sixth-inning home run as the true turning point, as it converted a competitive game into a comfortable Pittsburgh victory.
