MHSAA Winter Sports Start with Extended Basketball Schedules, New Wrestling Weights

The addition of two games to basketball regular-season schedules and a new series of wrestling weight classes are likely the most noticeable Winter 2022-23 changes as an estimated 65,000 athletes statewide take part in 13 sports for which the Michigan High School Athletic Association sponsors postseason tournaments.

Girls gymnastics and boys ice hockey teams were able to begin practice Oct. 31, with the rest of those sports beginning in November – including also girls and boys basketball, girls and boys bowling, girls competitive cheer, girls and boys skiing, Upper Peninsula girls and boys and Lower Peninsula boys swimming & diving, and girls and boys wrestling.

A variety of changes are in effect for winter sports this season, including a several that will be noteworthy and noticeable to teams and spectators alike.

Basketball remains the most-participated winter sport for MHSAA member schools with 33,000 athletes taking part last season, and for the first time, basketball teams may play up to 22 regular-season games. This increase from the previous 20-game schedule allows more games for teams at every high school level – varsity, junior varsity and freshman.

Another significant change has been made in wrestling, as the majority of boys wrestling weight classes have been adjusted for this season in anticipation of a national change coming in 2023-24. The updated boys weight classes are 106, 113, 120, 126, 132, 138, 144, 150, 157, 165, 175, 190, 215 and 285 pounds. Only 215 and 285 remain from the previous lineup. There is also one change to girls weight classes, with the 255 class replaced by 235 to also align with national high school standards.

A series of notable changes will affect how competition takes place at the MHSAA Tournament levels. In hockey, in addition to a new classification process that spread cooperative and single-school programs evenly throughout the three playoff divisions, the MHSAA Tournament will employ two changes. The Michigan Power Ratings (MPR) will be used to seed the entire Regional round, not just the top two teams, and prior to the start of Semifinals, a seeding committee will reseed the remaining four teams in each division with the top seed in each then facing the No. 4 seed, and the No. 2 seed facing No. 3.

Bowling also will see an MHSAA Tournament change, as the Team Regional format will mirror the long-standing Team Final with teams playing eight Baker games and two regular games at both levels.  And as also applied during the fall girls season, there is a new qualification process for divers seeking to advance to Lower Peninsula Boys Swimming & Diving Finals. In each of the three divisions, each Regional will be guaranteed 10 qualifiers for the Finals, with six more “floating” qualifier entries to be distributed to the Regionals that have one of the previous year’s top six returning Finals divers in their fields. If a team changes division from the previous season, any floating top-six spots are added to the six already allowed in the school’s new division.

A gymnastics rules change provides an opportunity for additional scoring during the floor exercise. A dance passage requirement was added in place of the former dance series requirement to encourage creativity and a more artistic use of dance. The dance passage requires gymnasts to include two Group 1 elements – one a leap with legs in cross or side split position, the other a superior element.

In competitive cheer, the penalty for going over the time limit in each round was adjusted to one penalty point for every second over the time limit, not to exceed 15 points. The new time limit rule is more lenient than the past penalty, which subtracted points based on ranges of time over the limit.

The 2022-23 Winter campaign culminates with postseason tournaments, as the championship schedule begins with the Upper Peninsula Girls & Boys Swimming & Diving Finals on Feb. 18 and wraps up with the Boys Basketball Finals on March 25. Here is a complete list of winter tournament dates:

The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.3 million spectators each year.  

Genesee's Zinn Setting School, Family Records While Climbing MHSAA All-Time Lists

Averie Zinn had a front-row seat as her sister Ryleigh re-wrote the Genesee girls basketball record book.

Bay & ThumbAs a middle school student, and then freshman teammate whose parents are the Genesee coaches, Averie saw exactly what it took for Ryleigh to get there.

She also had a pretty good idea of what would be required to overtake her.

“I remember when I was little I was like, ‘Yep, I’m breaking all her records,’” Averie said. “My mom’s sister, she held all of those before. But I just remember when Ryleigh was getting those records, I was like, ‘Well, I’m going to break them.’”

Averie Zinn has broken those records and then some, splashing her name across the MHSAA record book with most of her senior season still to go.

She’s scored a school-record 1,892 points during her career, and with a per-game average this season of 39.8, could surpass 2,000 by the end of next week – making her the 34th girls basketball player in state history to eclipse it.

If that average holds throughout the season, and even if the Wolves play the minimum number of games remaining, Zinn could become just the seventh female in the state to hit 2,500 points.

That, of course, is a projection of where she could be, but she already appears 20 times in the MHSAA record book.

Her 851 points scored a year ago are third highest in a single MHSAA season. Seven of her single-game scoring performances are listed, including five games of 50 or more (she’s added another 53-point performance already this season that is not yet listed). 

Her 21 points in a single quarter are tied for third all-time – she’s since hit 22, which will tie her for second. 

She made 186 free throws a year ago, 10th-most in a single season, and has three games of 15 or more makes from the free-throw line. 

Then there’s the steals: Two seasons in the top 12 all-time with 218 a year ago (third) and 170 as a sophomore (tied for 12th), and five games with 15-plus.

“I just think it’s such a blessing,” Zinn said. “No one really gets that opportunity, it’s such a select few amount of people. I almost don’t even think I’ve processed it. I think it’s really cool, and the fact that it’s happening with my parents coaching me, it’s really cool.”

Zinn elevates for a shot while defended by a pair of Panthers. Zinn, a 5-foot-10 point guard who also takes the opening tip for the Wolves, has scored 199 points through five games this season, going over 30 in four games and over 40 in two of those four. 

She’s recorded 48 steals, as well, going for double digits (11, 12, 16) in each of her first three games. 

“I mean, she’s 100-percent locked in,” said Genesee coach, and Zinn’s dad, Mike Zinn. “She’s been training hard with strength and conditioning, working on her range – a different range. Normally, she shoots from pretty deep, from nearly halfcourt like it’s nothing. But she’s been wanting to work on her mid-range game a little bit.”

As the Zinns have had their successes, so has the Genesee program. This year’s team is off to a 4-1 start, and last year the Wolves won a District title and advanced to a Regional Final in Division 3 for the second time in program history. The first came during the 2022 postseason.

Both of those seasons resulted in 17 wins, which is a school record.

The District title in 2022 was the program’s first since the mid-1990s, when their mom, Megan was playing.

“Mike and I graduated from Genesee High School, and we were the last ones to win a District title,” Megan Zinn said. “We decided to stay in the community, raise our kids in the community and coach here. It’s bigger than basketball. We believe we could work to put Genesee on the map, and that’s exactly what we’ve done. Last year, going to the Sweet 16 was the furthest we’ve ever gone. We lost both times, but just to say that we could get there while coaching both of our daughters is pretty special.”

When Averie Zinn is done breaking records at Genesee, she will continue her basketball career at Wayne State University. 

She committed this past summer to play for the Warriors, a program she’s felt connected to for years. Not only is assistant coach Andy Ayrault a family friend, but Zinn caught the eye of head coach Carrie Lohr while hitting deep 3-pointers as an eighth grader at a team camp.

“I’m really excited,” Zinn said. “I’m getting more and more excited, especially since the new year is here and knowing this is the year that I’m going away and playing there. I know a lot of my teammates already. Wayne State feels like another home to me. That’s what was most important in my decision.”

Genesee won’t be without Zinns, either. While Mike and Megan will continue coaching, there’s also another player coming through, as Averie and Ryleigh's younger sister Maylee Zinn will be a freshman next season.

“I’d say the (age) gap for me and Maylee is like one year too far,” Averie said. “Me and Ryleigh played together, we would go to trainings together. We got super close that year (they were teammates). I always say that to my mom, that I wish I was back a year so I could get that year with Maylee. She’s pretty good.”
