Ibaka returned to the court after missing two games with a calf injury, and he quickly made his presence known on Sunday. Leonard got him on this one, though, driving hard through the paint and elevating quickly before Oklahoma City's shot-blocking specialist could contest the try.
With a little more than eight minutes remaining in the third quarter and Oklahoma City leading 67-57, Tony Parker swung the ball to Leonard on the right wing. Leonard attacked the center of the court, with Kevin Durant overplaying his left hand, and he kept going once he hit the paint and encountered no resistance.
Taking off from outside the protected circle, Leonard simply coasted until he finished the one-handed dunk over Ibaka, who came over from the right block a split-second too late.
Leonard might have won the battle on this play, but Ibaka and the Thunder won the war. Ibaka finished with 15 points (on 6-for-7 shooting), seven rebounds and four blocks in his first action of the series, helping power Oklahoma City to a convincing victory.
Russell Westbrook led the Thunder with a game-high 26 points (on 8-for-19 shooting), eight rebounds and seven assists. Durant added 25 points (on 8-for-19 shooting), 10 rebounds and three assists in the win.
Leonard posted 10 points, three rebounds and two assists for San Antonio. Manu Ginobili led the Spurs with a team-high 23 points (on 8-for-13 shooting) and four assists in a losing effort.
