 If no one is covering home (both batters are running), then the runner advancing homeward can be put out by throwing the ball to the plate before the runner gets there - a practice called "crossing out".In still another variation, a volleyball or similar ball may be used and there will be no pitcher.The "up" player sets the ball in motion by holding it in his or her non-dominant hand, and sets it in motion by a hefty strike from the other hand.
