If the batted ball hits the screen for the first time in an at bat, it becomes a foul ball. If the ball hits the screen a second time, it is a dead ball out. If the ball “must be fair” and hits the screen, it is a dead ball out

If there is an attempt to tag the runner, then the runner is automatically safe.
- Sliding or diving headfirst is not allowed when going to first base or home plate; the runner will be ruled out. Sliding or diving headfirst is allowed when returning to first base, or at any time involving second or third base.
