Below is this week's segment - Pitcher Arm Care - Listen
Health and safety continues to be the major focus of the MHSAA. One rule that is geared directly to player safety is our baseball pitching limitation rule of 30 outs.
The 30-out rule limits the number of innings, or outs, that a pitcher can throw in both a given day as well as over a period within a week.
We want to make sure that high school coaches are not overusing their pitchers; that they are finding that safe area, to where arms have the ability to recover after a player has pitched a certain number of outs, allowing the body to recover so that player can have a safe and enjoyable season.

Be the Referee: Tennis Double Hit

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.
