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.

Be the Referee: Block/Charge Calls
March 29, 2016
This week, MHSAA assistant director Mark Uyl explains what is often considered the most difficult call to make in all of sports officiating.
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 - Block/Charge - Listen
It’s often been said that the most difficult call to make in all of sports officiating is the block/charge in basketball.
When you’re watching your next basketball game, the key for the official in getting the play correct is determining whether or not the defender gets in a legal guarding position. Many times we’ll hear announcers and commentators talk about the defender having his feet planted and stationary; that actually isn’t required by the rule. The rules require the defender to be in a legal guarding position, which is a position where it’s facing the offensive player and they’ve established a position in advance of the offensive player.
If the defender is in illegal position, the contact is now a charge.
