Westbrook poured in 29 points with 11 assists and 12 rebounds. Victor Oladipo added 23 points and seven rebounds and center Steven Adams of New Zealand added 21 points and 13 rebounds for Oklahoma City, who improved to 31-23. Kyrie Irving led the Cavs with 28 points. LeBron James chipped in 18 to go with seven assists but was held scoreless in the fourth quarter. Irving's layup tied it at 99-99 with less than six minutes remaining, but two Westbrook baskets put Oklahoma City up 103-99 with 4:59 to play. Irving answered with a driving layup, but after a Westbrook jump shot, Thunder reserve Jerami Grant blocked a shot at the other end. Westbrook sank another jumper to stretch Oklahoma City's lead to 107-101 with 3:42 remaining. James missed a fadeaway jumper before Westbrook fed Adams for an easy basket. After another block, Westbrook had the ball again, dishing to Oladipo for a layup that gave Westbrook his 10th assist and clinched his triple-double.
