A 31-point game from Kevin Durant has helped Oaklahoma City to a 95-79 victory over the Dallas Mavericks to stretch the series lead to 3-0.
Oklahoma were never behind in a match they comfortably dominated and Dallas now face a near impossible task to keep the defence of their NBA title alive.
Durant produced his best perfomance of the series as he repeatedly caused problems for the hosts and he looked close to his early season form at the American Airlines Center.
Russell Westbrook added 20 points for Oklahoma as Dirk Nowitzki top scored with 17 points for the Mavericks.
Oklahoma will secure a series triumph with a win in the next game on Saturday.
