Seattle Mariners at Detroit Tigers: Final Score & Recap

The Detroit Tigers walked off the Seattle Mariners 5-4 at Comerica Park on June 7, 2026, in a game that the DiamondIQ model gave Detroit only a 43% chance of winning before first pitch. Seattle built leads through a run in the third, two more in the sixth, and one in the seventh, carrying a 4-3 advantage into the bottom of the ninth with closer Andrés Muñoz on the mound. What followed was the single most consequential sequence of the game. Wenceel Pérez drew a leadoff walk against Muñoz, a play the DiamondIQ model measured at a +12.3% swing in Detroit's win probability, and Kevin McGonigle then lined a walk-off single that registered +78.8% win probability added, the largest swing of the contest by a wide margin and the play that moved the model's estimate to 100% in Detroit's favor.

McGonigle was the unquestioned driver of the Tigers' victory, finishing with a cumulative WPA of +91.5% and a RE24 of +2.6. His contributions bookended the game: a solo home run off Luis Castillo in the bottom of the fourth added +11.9% to Detroit's win probability, and his ninth-inning single closed it out. Zach McKinstry supported him with a +22.0% WPA performance, and Pérez contributed +19.4% WPA including the pivotal walk that set the table in the ninth. On the pitching side, Eduard Bazardo led Detroit's staff with +23.3% WPA out of the bullpen, working through the eighth despite a Zack Short flyout that the model tagged at -12.9% for the Tigers. Seattle's Luis Castillo posted +11.0% WPA in a losing effort, while Gabe Speier added +9.7% in relief, but neither was enough to prevent Detroit from completing the comeback on McGonigle's final swing.
