The feat was a sixth of Westbrook's career and helped the Thunder rally from a five-point deficit in the final frame and bounce back for the victory, which followed a Friday loss to Minnesota.
Kevin Durant (30 points, eight boards, five assists) and Serge Ibaka (16 points, eight blocks) also played key roles in the victory.
Ersan Ilyasova supplied 29 points and 14 rebounds for the struggling Bucks, who lost for the fifth time in six games.
