GIF: Cardinals walk off over Mariners on passed ball

The St. Louis Cardinals earned a 2-1 victory over the Seattle Mariners on Friday night thanks to Mariners catcher Mike Zunino's passed ball in the bottom of the tenth inning.

Matt Holliday was at the plate with the bases loaded, but his services were not required, as Pete Kozma raced home from third with the game-winning run.

With the win and the Pittsburgh Pirates 5-4 loss to the Chicago Cubs, the Cardinals now lead the National League Central division by a full game.
