Be the Referee: Bat Safety

June 1, 2015

This week, MHSAA assistant director Mark Uyl explains how bats have been altered the last few seasons to make baseball safer for pitchers and infielders.

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 - Bat Safety - Listen

The biggest change in the world of amateur baseball over the last five years has been the new standards for non-wood, or what most of us refer to as aluminum, bats.

Prior to these changes, it was quite common to see high school and college baseball scores in double digits on a regular basis. 

The new bat standards first sought to address player safety. And now these new aluminum bats match the ball exit speed ratio – or in other words, the speed that the ball comes off the bat – for a non-wood bat with what it would be coming off a wood bat; making the amateur game safer for pitchers and infielders.

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.
