After hitting two free-throws to give the Thunder a 110-106 lead, Russell Westbrook skied to block a Devin Booker layup attempt to seal the win.

Westbrook secured the rebound and flashed a thumbs down in triumph—similar to Serge Ibaka’s new block celebration—which Suns forward PJ Tucker likely viewed as a taunt.

Were it not for Kevin Durant who stepped in to settle Tucker down, things could have gotten out of hand.
