Doors open at 7:30 a.m., with the first session at 9 a.m. at DeVos Place. The day-long event will feature dynamic speakers and presenters providing knowledge in several sports and all levels including collegiate and professional. We will be highlighting several of those speakers over the next many weeks on MHSAA.com and social media as part of the lead-up to the event.
Cost is $45 if officials register by the end of June, and $50 beginning July 1. More information is on the way; keep posted at MHSAA.com/OMD.
This will be the third Officiate Michigan Day, joining events in 2013 and 2018.
OMD will accompany the annual National Association of Sports Officials (NASO) Summit that will take place July 26-28, also at DeVos Place.
Be the Referee: Bowling Ball Rules

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 – Bowling Ball Rules - Listen
We’re bowling today, and the question is: Can a bowler use a bowling ball with no holes?
The answer is yes – but there are some rules around it.
A ball with no holes would have to follow static balance rules. If the ball weighs more than 10 pounds, it may not have more than three ounces of difference between any two halves of the ball.
Additionally, there needs to be a plus sign (+) engraved on the ball where the bowler will place their dominant hand if the ball has more than a three-quarter ounce imbalance between any two halves of the ball.
If there is no imbalance, the plus sign is not needed, and the bowler can place their dominant hand anywhere on the bowling ball they like.
