The Marlins trailed 7-3 entering the game's final frame. A bases-loaded error followed by a triple from the reigning American League batting champion Luis Arráez set the stage for Burger to drive home the game-winning run.
He did just that, ripping an 88 mph changeup off of Tommy Kahnle to left field for the victory.
