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.

Be the Referee: Tennis Double Hit

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 – Tennis Double Hit - Listen

We’re on the tennis court today, returning a ball that our opponent has hit.

We swing, hitting the ball with the strings and then again with the frame of the racket as our swing continues.

The double-hit ball goes over the net and bounces past our opponent for a point. Or is it our point? Can you hit the ball twice?

You can, if it’s all part of one continuous swing. You can hit the ball more than twice even – as long as it’s the same swing.

You can’t intentionally hit the ball twice or hit the ball and then re-hit it. It’s illegal if you deliberately catch or carry the ball and then hit it again.

But if your double-hit is part of one smooth swing, the stroke counts and play continues.
