With just over 40 seconds left to play in a fairly meaningless game between the playoff-bound Oklahoma City Thunder and the lottery-bound Los Angeles Lakers on Tuesday, Isaac Bonga, a 19-year-old Lakers rookie, badly missed a 15-foot shot. Russell Westbrook, the veteran Thunder guard, snatched the ball out of the air for a defensive rebound.

“That’s for Nipsey!” he declared, referring to the rapper Nipsey Hussle, whose fatal shooting over the weekend seemed to shake many N.B.A. players.

Westbrook’s presence on the floor in the closing moments of an easy 119-103 home victory for the Thunder would usually have been odd, but on this night the modern master of the triple-double was out there to grab his 20th rebound of the night.

Combined with his 20 points and 21 assists, the rebound made Westbrook the second 20-20-20 player in N.B.A. history, according to the Elias Sports Bureau. He joined Wilt Chamberlain, who had 22 points, 25 rebounds and 21 assists on Feb. 2, 1968.
