Kevin Durant, Russell Westbrook and the Thunder gave the Warriors as complete a beating as they experienced during their record-setting season.
Suddenly, a second straight title seems to be anything but a given for Golden State. Now the Warriors are just trying to survive.
Durant scored 33 points, Westbrook had 30 points, 12 assists and eight rebounds, and Oklahoma City rolled to a 133-105 victory on Sunday night to take a 2-1 lead in the Western Conference finals.
Durant made 10 of 15 shots and Westbrook was 10 of 19. It was the first time this postseason both players shot better than 50 percent from the field.
Serge Ibaka added 14 points and eight rebounds for the Thunder, who matched a franchise record for most points scored in a playoff game.
Golden State's Draymond Green, who kicked Oklahoma City's Steven Adams in the groin and has become Thunder fans' No. 1 target because of some questionable tactics, struggled on both ends of the floor and finished with six points on 1-for-9 shooting.
Stephen Curry shot 4 for 13 in the first half, Klay Thompson went 5 for 14 and Green 1 for 8.
