Deron Williams, who had 22 points, pulled Dallas within one with a 3, and Durant answered with a jumper. After Wesley Matthews missed a shot from long range, he drew a foul coming around a screen from Serge Ibaka to give the Mavericks another chance.
Williams made a mistake by trying to shoot from inside the arc, but ended up with the loose ball after Ibaka blocked it.
