The balls were flying at Clayton Kershaw's charity ping pong tournament on Thursday ... and if you've ever wanted to see your favorite celebs freaking out over some table tennis, you're in luck.
The Dodgers ace -- rockin' a retro outfit that would make the '80s proud -- hosted his closest celeb friends for the super competitive tourney at Dodger Stadium ... and it's clear nobody's taking it easy.
This year's tourney had Matthew McConaughey, Mila Kunis and Ashton Kutcher, Bryan Cranston ... and a bunch of Dodgers stars like Justin Turner and Austin Barnes.
