The St. Louis Cardinals held on to defeat the Pittsburgh Pirates 5-4 at PNC Park on April 29, 2026, completing a come-from-behind road win that the DiamondIQ model gave Pittsburgh just a 49 percent chance of winning before first pitch. The Cardinals scratched across the game's first run in the third inning before Alec Burleson's fifth-inning home run off Bubba Chandler proved to be the pivotal offensive moment of the contest. That swing carried a win-probability swing of plus-19.8 percent in St. Louis's favor and gave Burleson a game-high RE24 of plus-1.6, reflecting how significantly it altered the run-expectancy landscape. Pittsburgh responded to cut into the deficit, and a Bryan Reynolds walk off JoJo Romero in the seventh — worth plus-12.1 percent in win probability — kept the Pirates' hopes alive as the two clubs traded a pair of runs that frame to make it a one-run game entering the late innings.
Pittsburgh mounted its most dangerous threat in the eighth, when a Spencer Horwitz walk off George Soriano added plus-11.5 percent to the Pirates' win probability and brought the tying run to the plate. Soriano and the Cardinals' bullpen ultimately extinguished that rally, however, and it was the ninth inning that delivered the game's single most consequential moment in reverse. Nick Gonzales's flyout to end the game against Riley O'Brien shifted win probability plus-27.0 percent back toward St. Louis, cementing the Cardinals' one-run victory. A lineout by Nick Yorke in the eighth, which cost Pittsburgh 23.3 percent in win probability, had already signaled how close this game came to slipping away from St. Louis. Andre Pallante led all pitchers with a plus-19.4 percent WPA contribution, while Gonzales finished as the top batter by that measure at plus-28.4 percent despite a RE24 of minus-0.4, a reflection of how heavily his final at-bat weighted a game decided on the thinnest of margins.
