Owner of State's All-Time Farthest Shot Put Aiming for National Record, Olympics

From the first time Montrose's Addyson Stiverson picked up the shot put at a sixth-grade track & field practice, it was clear there was something there.
Even if she wasn’t quite clear on the name.
“I ran at the first couple practices, and was like, this wasn’t for me,” she said. “They said, ‘You’re strong, try the heavy ball thing.’ I honestly never threw it like a baseball. It wasn’t impeccable, but I kind of knew the basics. I definitely had some sore elbows and shoulders.”
Five years later, Stiverson sits atop the record books as she’s thrown that heavy ball thing farther than any female in Michigan high school history.
Her personal best of 53 feet, 7½ inches, which she threw Dec. 13 at an indoor meet at Grand Valley State University, is nearly two feet farther than the previous record of 51-11 held by Byron great Sarah Marvin, according to MichTrack.org, which tracks records from all meets. (The MHSAA record book is for Finals meets only.)
And as she enters her junior outdoor season having already won the shot put twice and discus once at the Lower Peninsula Division 3 Track & Field Finals, Stiverson’s goals go well beyond the state’s borders.
“(Competing in the Olympics) is the goal,” Stiverson said. “Throwing in 2028 would be nice, but I think a good goal is to be a good contender in (2032). Even going to trials in 2028 and getting close to making the team would be a big win for me.”
It’s a huge goal, but not at all outlandish for Stiverson, who is already fielding scholarship offers from between 20 and 30 major Division I programs and is part of the Nike Elite Team, which includes 40 of the country’s top high school track & field athletes.
She also trains with Dane Miller at Throws University in Reading, Pa. Miller has trained two national champions and 12 World Team members.
“When he texted me like a month or two after we went out there and he was like, ‘I want to coach you,’ I was like, holy crap. I was kind of fan-girling for a moment,” Stiverson said. “He’s like one of the only reasons I throw as far as I do. When he first started coaching me, he was like, you’re not doing this anymore, we’re doing this. He cut out all the bad stuff.”
Stiverson’s 53-7½ would rank seventh all-time on the National Federation of State High School Associations list. The listed record there is 57-1¼, by Alyssa Wilson of New Jersey. But Wilson threw 58-1 during the summer after her senior year, and that’s the record Stiverson is chasing.
Plus a little more.
“She always has that goal in the back of her mind of breaking that 58-1,” said Adam Stiverson, Addyson’s father and Montrose’s girls track coach. “She kind of has a little future goal that no one really talks about it: Could a high school female thrower ever hit 60 feet?
“She wants to compete in college no matter what, and she wants to get better. There’s always room for improvement. If she can fix some things, get a little bigger, a little stronger, 60 feet could be possible. But let’s get 55 feet out of the way, 56 feet out of the way, 57 feet out of the way. If we can get to 57, then we can talk about that 60, because then we’d know that 58-1 is coming.”
While chasing down national goals, Stiverson has been dominating locally.
She’s never been beaten in the shot put during the high school season, and she’s never finished lower than third in the discus, despite it being much less of a focus for her, as she doesn’t want it to affect her form in the shot.
“I’m not going to lie, I don’t touch a disc that much,” Stiverson said. “I give it maybe 75-25, maybe 70-30 during the season. I feel like if I give it too much attention, it could mess up my shot.”
While throwing is her main focus now, Stiverson did play varsity basketball as a freshman and sophomore at Montrose. She also played football all the way through freshman year.
At 5-foot-9, her all-around athletic ability and explosiveness are a great base for her throwing ability, and while she hasn’t shown it off in a while, she can run, too.
On the day she set the Montrose school record for the shot put as a freshman, she also won the 100 meters at a Mid-Michigan Activities Conference quad meet.
“That was for team points,” Stiverson said with a laugh. “Our coach said, ‘One of the girls didn’t show up, we need you to run.’ And I had my spikes with me, so I did.”
Stiverson was the Division 3 Finals champion in the shot put both of the past two years, and won the discus in 2025 as well. She was runner-up in the discus as a freshman.
There are still two full seasons to go, but she’s on pace to become the first female thrower in the Lower Peninsula to win four Finals titles in the shot put.
“I think that was my biggest goal when I came into high school; I wanted to be a four-time shot put state champ,” she said. “When it does happen, that would be one of the coolest things. That was a dream.”

Lacrosse Finals Move to U-M Among Headlines as Spring Sports Ramp Up

The Girls & Boys Lacrosse Finals will be played at University of Michigan Lacrosse Stadium for the first time, one of the most notable changes for this season as sports ramp up for more than 100,000 athletes anticipated to participate this spring for Michigan High School Athletic Association member schools.
The MHSAA sponsors postseason competition each spring in baseball, girls and boys lacrosse, girls soccer, softball, girls and boys track & field, boys golf (Lower and Upper Peninsula) and girls golf (UP), and girls (LP) and boys (UP) tennis.
The U-M Lacrosse Stadium opened for competition in 2018 and seats 2,000 spectators. The Girls Lacrosse Finals will be played Friday, June 7, with Division 1 at 4 p.m. and Division 2 at 7 p.m. The Boys Lacrosse Finals will be played the following day, June 8, with Division 2 at 11 a.m. and Division 1 at 2 p.m.
Girls lacrosse also has a significant format adjustment this season, as games will be played with four 12-minutes quarters instead of the previous two halves, in part to allow coaches more opportunities to provide direct instruction during a game. Two more rules changes are expected to improve flow of play – players awarded a free position outside of the critical scoring area no longer must come to a stop and settled stance before self-starting, and false start penalties outside the critical scoring area have been eliminated.
Several more rules changes will be noticeable this spring:
In boys lacrosse, a change was made to enhance player safety. Play will stop immediately any time a player’s helmet comes off, and that player may not return until the next dead ball after play continues.
Fair and legal starts are a continued emphasis for track & field, and a rule change will allow for movement before the start of the race as long as a competitor does not leave their mark with a hand or a foot after the “set” command, or make forward motion before the starting device is activated.
A significant rule change in softball alters pitch delivery mechanics. The pitcher may now have both feet off the ground at the same time when releasing the ball as long as both feet remain within the 24-inch width of a pitching plate and the pitcher does not replant the pivot foot before delivering the pitch.
Another change in softball requires that a playbook/playcard be worn on the wrist or kept in a back pocket to reduce distractions. If worn by the pitcher, the equipment must be worn on the non-pitching arm. Similarly in baseball, a wristband with plays or instructions will be permitted but must be a single, solid color, and for pitchers may not contain the colors white or gray or be otherwise distracting. Baseball players must wear this wristband on the wrist or forearm, and pitchers may wear one only on their non-pitching arm.
Also in baseball, a rule change allows for one-way communication devices worn by the catcher to receive instructions from the dugout while on defense, for the purpose of calling pitches. The coach must be inside the dugout/bench area to use the communication device.
Golfers now are required to participate in at least four competitions for the high school team prior to representing that school team in an MHSAA Regional or Final. Those four regular-season competitions may be 9 or 18-hole events.
In tennis, for the first time in Lower Peninsula play, a No. 1 doubles flight from a non-qualifying team will be able to advance from its Regional to Finals competition. To do so, that No. 1 doubles flight must finish first or second at its Regional, and the No. 1 singles player from that team also must have qualified for the Finals individually by finishing first or second in Regional play.
On the soccer pitch, two officiating-related changes will be especially noticeable. Officials now may stop the clock to check on an injured player without that player being required to leave the match – previously that player would have to sub out. Also, categories for fouls have been redefined: careless (which is a foul but does not receive a card), reckless (a foul with a yellow card) and excessive force (foul with red card).
The 2023-24 Spring campaign culminates with postseason tournaments, as the championship schedule begins with the Upper Peninsula Girls & Boys Golf and Boys Tennis Finals during the week of May 27 and wraps up with Girls Soccer, Baseball and Softball Finals on June 15.
