The vibes were at an all-time high after the Philadelphia Phillies secured their spot in the playoffs ... and outfielder Brandon Marsh was the MVP of the party -- even hopping on a mechanical bull to celebrate the big moment!!
The defending National League champs clinched the top wild card spot after a walk-off win over the Pittsburgh Pirates on Tuesday ... and Marsh -- who had a homer in the effort -- led the charge as the squad let loose after the game.
The Phils jumped up and down in the locker room as the champagne flew through the air .
