Russell Westbrook Dedicates Historic 20-20-20 Game to Nipsey Hussle

Russell Westbrook was playing for Nipsey Hussle when he went OFF in his historic performance on Tuesday night ... dedicating his 20-20-20 game to the slain rap star.

The NBA MVP became the first player to have 20 points, 20 assists and 20 rebounds in a game since Wilt Chamberlain (in 1968) in the Thunder's 119-103 win over the Lakers ... and he explained the symbolic meaning to the milestone.

"20 plus 20 plus 20 .... they know what that means," Brodie told Jason Terry on the TNT broadcast. "That's for my bro. Rest in peace, Nipsey." Brodie said after the game.

Of course, Westbrook is referencing Nipsey's Rollin 60s Neighborhood Crips gang.

Brodie, who grew up in the L.A. area and was close to Nipsey ... and knew firsthand how important he was to the community.

"Grateful to play the game, but that wasn't for me, man. That was for my bro, man. That was for Nipsey."

"I'm just thankful to go out there and compete at a high level, man. Thankful to have these teammates. Thankful and humbled to go out there and play the game I love."

Westbrook also showed tribute to Nipsey with his clothing choice before the game, rocking a blue "Crenshaw" shirt, as well as writing a message on his shoes.

Brodie finished the game with 20 points, 20 assists and 21 rebounds.
