Be the Referee: Pitcher Arm Care
June 8, 2015
This week, MHSAA assistant director Mark Uyl explains how the 30 out-limit rule works to keep baseball pitchers' arms healthy.
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 - 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.

What's My Why: Official Cindy Tyzo
June 8, 2026
Cindy Tyzo, West Bloomfield
Tyzo is one of what surely are only a handful of officials who have been registered for two MHSAA-sponsored sports since their first seasons as part of the championship lineup. She's is completing her 33rd year overall after first registering for the inaugural season of competitive cheer in 1993-94, and she also officiated the first season of MHSAA field hockey this past fall.
Tyzo also just completed her eighth season officiating girls lacrosse.
I love officiating because I love working with the young people and providing the opportunity for them to do the sport that they love. Because without officials, there's not game.
“What’s My Why” is a weekly feature telling the stories of MHSAA-registered officials in their own words. If you’re an MHSAA official and would like to share your reason why, please submit a 15 to 45-second video, taken horizontally, to director of officials Sam Davis at [email protected].
