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.

What's My Why: Official Kari Seitz

August 19, 2026

Kari Seitz, Mill Valley (Calif.)

Kari Seitz – the closing speaker at July’s Officiate Michigan Day in Grand Rapids – was one of the top American professional soccer referees and one of the most experienced female referees in the world. She is currently the vice president of refereeing for US Soccer and formerly served as the FIFA head of refereeing.

She worked four FIFA Women's World Cup tournaments (1999, 2003, 2007, and 2011), as well as three Olympic soccer tournaments (2004, 2008, and 2012), and is the only referee – man or woman – to officiate that many of both. Kari was inducted into the National Soccer Hall of Fame in 2026 and is a graduate of Brighton High School and Michigan State University.

So I was a soccer player, played soccer since I was 6. And at some point, I joined an all-girls travel team – that never happened. This was a long time ago.

Our coach required us together, every person on the team, to take the (officiating) course. Now, I believe he didn’t know anything about soccer. He was one of those parents who was reading it from a book and just cared about his kids. So he forced us all to take the referee course, and that altered the path of my life.
