Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.

Below is this week's segment – On the Line - Listen

I’m on the line today … but am I in or out?

Have you ever stopped to think about how the boundary lines of a field or court mean different things in different sports?

In basketball for example, if the ball touches the baseline or sideline, it’s out of bounds. Same if a player is in possession of the ball and touches the line.

Football is the same. A player is out of bounds if that player has the ball and touches the sideline.

But in soccer? The ball is still in play until it completely passes the line. If the ball is sitting on the line, it’s still in play.

A tennis ball on the line? That’s in and a great shot.

Volleyball? Also in.

And then you have baseball and softball – where a batted ball that hits the foul line … is fair.

Know the lines and you’ll always know if you are in … or out.
