Special Olympics: Amazing Buzzer Beater ... In Thrilling Hoops Finish!

This is awesome!!

Amazing finish at a Special Olympics high school basketball game in Washington Monday night -- when one of the players hit a shot with time winding down to win the game ... AND THE CROWD GOES WILD!!!

The big hero is Dustin Walston of Sumner High ... who got the ball in his hands with the score tied at 32 in a thrilling game against state powerhouse Rogers High School.

But as time expired, Walston didn't buckle under the pressure -- he summoned his inner Steph Curry ... and hit the game winner!!!

Congrats to both teams -- but mad props to Walston!!
