With just under seven minutes left in the Raptors' 100-94 victory over the Bucks, Raptors point guard Kyle Lowry quickly dribbled down the court. Lowry stopped as he neared the basket and passed behind him to a sprinting Leonard.
Leonard jumped and, with one hand, slammed the ball in over Antetokounmpo.
Leonard finished Saturday's win with 25 points, 17 rebounds, and seven assists.
Leonard and the Raptors will play the Golden State Warriors in the NBA Finals.
Game 1 of the NBA Finals will be played at Scotiabank Arena in Toronto on Thursday, May 30. The game will air on ABC.
