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.

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: Field Hockey Substitutions

By Paige Winne
MHSAA Director of Brand Management

October 27, 2026

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 – Field Hockey Substitutions - Listen

We’re on the pitch today for a field hockey “You Make the Call.”

The white team is awarded a penalty corner. During the penalty corner, a red team substitute enters the field but does not participate in or affect play.

Should the official stop play immediately or allow play to continue?

If you said allow play to continue, you are correct. Since the illegal substitute has not participated in or affected play, stopping play immediately would give the defending team an unfair advantage by interrupting the attacking team's scoring opportunity.

Under NFHS Rule 4-4-3, substitutions are not permitted during a penalty corner, except to replace an ill, injured, suspended or disqualified goalkeeper. Officials must recognize the violation and know when to hold the whistle to allow for advantage.
