What is the only sport in which the ball is always in the possession of the team on defense, and the offensive team can score without touching the ball?

In baseball, the defensive team (fielding) always has possession of the ball. The offensive team (batting) can score runs by hitting the ball and then running around the bases without ever touching the ball again. This unique structure makes baseball the only sport where the ball is always with the defense and offense can score without touching it.
