Detroit Tigers at Pittsburgh Pirates: Final Score & Recap

The Pittsburgh Pirates walked off the Detroit Tigers 4-3 on August 19, 2026, at PNC Park in a game that appeared destined for a different outcome before a stunning ninth-inning collapse by Detroit's closer. The DiamondIQ model's estimate opened at a 55 percent home win probability for Pittsburgh and closed at 100 percent, reflecting just how complete the Pirates' late takeover was.

The decisive sequence came in the bottom of the ninth against Kenley Jansen, who surrendered back-to-back home runs that swung the game's win probability by a combined 93 percentage points. Rafael Flores Jr. connected first, a blast that shifted Pittsburgh's chances by plus-47.1 percent, then Brandon Lowe followed immediately with a home run of his own for an additional plus-45.9 percent swing, completing the two-run walk-off. Flores Jr. had already done damage in the seventh inning, a solo home run off Jacob Waguespack worth plus-15.6 percent in win probability, giving him a game-high plus-62.7 percent WPA and a plus-2.0 RE24 on the night. Lowe finished at plus-43.7 percent WPA and plus-1.1 RE24. Detroit had its own moments of opportunity, most notably Gleyber Torres drawing a single off Paul Skenes in the fifth that generated plus-12.9 percent in win probability as the Tigers built what briefly looked like a comfortable advantage.

Pittsburgh's pitching staff did considerable work to keep the Pirates in range before the offense delivered. Kyle Finnegan led all pitchers with plus-23.3 percent WPA, followed by Jackson Jobe at plus-20.3 percent and Luke Weaver at plus-7.4 percent. The lone negative moment for the Pittsburgh offense was Nick Yorke's flyout in the eighth against Finnegan, a minus-22.1 percent swing that nearly extinguished the Pirates' hopes before Flores Jr. and Lowe made it irrelevant.
