In the win at the Thunders' 119-103 home over the Lakers, Westbrook became the second player in league history to have 20 or more points, rebounds and badists in a game. He finished with 20 points, 20 rebounds and 21 badists.
Wilt Chamberlain was the only other player to achieve the feat, scoring 22 points, 25 rebounds and 21 badists in a 1968 game.
Westbrook dedicated the game to Hussle, who was shot dead at the South L.A. store. Sunday afternoon.
"That was not for me, man, it was for my brother, it was for Nipsey," Westbrook said after the game. "20 plus 20 plus 20. They know what that means. That is for my brother. Rest in peace Nipsy.
"I'm not going to try to put it into words, but like I said on the floor, that's what it's for," Westbrook added. "I'm going to leave it like that."
Like Hussle, Westbrook was born and raised in L.A. He played his college basketball at UCLA.
On Tuesday, Eric Holder, a 29-year-old gang member suspected of shooting Hussle, was captured in Bellflower.
