Kevin Durant scored 36 points and had 10 rebounds, while Russell Westbrook 25 points and nine boards to save the season for the Thunder.
The pair put an exclamation point on the win with this highlight.
History is on the Thunder's side heading into game seven. Of the 114 game sevens in NBA history, the home team has won just under 80 percent of the time.
Pretty good odds for OKC to be in the second round this weekend.
