L.A. Dodgers Have Insane NLDS Celebration With Beer Baths And Patriotic Speedos!!

It's safe to say there wasn't a dry spot in the Dodgers' locker room Thursday night ... as L.A. celebrated its NLDS-clinching win with a TON of beer, champagne and Josh Reddick in an American flag Speedo!!

The Dodgers scored 4 runs in the 7th inning of Game 5 of the NLDS to beat the Washington Nationals 4-3 ... and the boys went all out with their post game party.

Check out the pics ... these guys definitely know how to turn up.

Next up, the red hot Cubs, so we're assuming they got it all out of their system and are ready to get back to work.
