Aug. 16 -- Bryce Harper obliterated an inside fastball for a gargantuan walk-off grand slam to lead the Philadelphia Phillies to a dramatic comeback win against the Chicago Cubs in Philadelphia.

"Besides winning the division and getting to the playoffs, that was one of the coolest moments I've had in my life," Harper told NBC Sports Philadelphia.

The Phillies entered the bottom of the ninth inning trailing 5-1 Thursday at Citizens Bank Park. Phillies shortstop Jean Segura began the bottom of the frame by flying out to left field. The Cubs allowed Cesar Hernandez to reach base on a fielding error in the next at-bat. Scott Kingery followed with a single off Cubs reliever Rowan Wick. Brad Miller plated Hernandez with an RBI single in the next at-bat, giving Philadelphia its second run.

The Cubs pulled out Wick for Pedro Strop to face the Phillies' Roman Quinn. Quinn singled to score Kingery before Strop hit Hoskins with a pitch in the next at-bat, loading the bases for Harper.
