Below is this week's segment – Tennis Nets - Listen
Let’s talk tennis… specifically, the rules around the net.
First – tennis nets are 42 inches high at the posts and 36 inches high in the center. And nets measure 42 feet wide.
Players and their equipment CANNOT touch the net during a point. However, a player’s follow-through can cross over the net if the ball was hit to the correct side of the court. But no part of the follow-through can touch the net.
Also, the ball must completely cross the net before it can be hit. If your opponent hits a high lob and you are standing at the net ready to smash a return – you must wait until the ball is completely over the net before hitting it.
Making contact with the net during play or hitting the ball before it’s over the net results in a loss of point.

Be the Referee: Illegal Substitution/Participation

Below is this week's segment – Illegal Substitution/Participation - Listen
We’re on the football field this week with 23 players.
Twenty-three is one too many; there should only be 22 on the field at once – 11 on offense, 11 on defense.
But on this play, the offense had a 12th player lined up on the field.
What’s the call?
It depends on when the penalty is spotted.
If the officials catch it before the play is run, that’s an illegal substitution and a 5-yard penalty.
But if the ball is snapped and a play is run with 12 on the field – and the 12th player is not attempting to get off the field – then it’s illegal participation and a 15-yard penalty. It’s also a 15-yard penalty if the offense uses a substitution to create a deception.
