Oscar Robertson is the only player to have more triple-doubles in an NBA season than Russell Westbrook, who had his 31st of the campaign in Oklahoma's 102-92 victory over San Antonio.
Westbrook had 23 points, 13 rebounds and 13 assists to match Wilt Chamberlain's 1967-68 season and be 10 off Robertson's 41 during the 1961-62 season.
"It's a blessing, man," Westbrook said. "You come out every night and compete and try to compete at a high level.
"Whenever you are mentioned with guys like that, it's always a blessing. I don't take it for granted."
Kawhi Leonard scored 19 points for the Spurs, but he took a hit in the head and neck area on a drive to the hoop and he didn't play in the fourth quarter.
