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.

Bay & ThumbEven 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.

Montrose's Addyson Stiverson competes in the shot put at last season’s LPD3 Finals.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.”

VanderKooi & Friends Deliver Western Michigan Christian's 1st Track Title

HUDSONVILLE – Abby VanderKooi just needed a little help from her friends.

The Muskegon Western Michigan Christian senior distance runner convinced her friends, volleyball standouts Kyla and Maddie Wiersema, to join the track team in their senior year to give WMC an added boost at the end of the season.

At Saturday’s Lower Peninsula Division 4 Finals, Kyla scored in three events, while Maddie scored in two. That, combined with VanderKooi scoring in four of her own, gave the Warriors the lift they needed to win their first track & field Finals title, posting 52 points to finish just ahead of 2021 champ Mount Pleasant Sacred Heart, which scored 48.

“They’ve been friends since they were little kids, so they decided to come out this year,” WMC coach Greg Gould said of the Wiersema twins and VanderKooi. “We knew they were super talented and just added a lot to this team. To see them perform so well (Saturday) and help this small team of athletes win a state title is pretty incredible.”

VanderKooi herself had a big day, setting an LPD4 Finals record in the 3,200-meter run with a time of 10:49.25. It was her third time winning a Finals title in the event to go with four cross country state titles as well.

She also finished second in the 1,600, fourth in the 800, and was part of the 3,200 relay team that finished second.

“Today wasn’t about me, it was about what I could do for my team,” VanderKooi said. “I’m really happy with my performances, but I’m most excited about what we’ve been able to do as a team.”

The Irish had a big performance from senior Nicole Olivieri, who won the 200 in a time of 26.37, then set an LPD4 Finals record in the 400 with a time of 56.01. She was also the anchor leg of the winning 800 relay team (1:49.21) and the runner-up 1,600 relay squad.

“I was pretty tired after that 400, but I knew my team was depending on me for points in the 200, so that gave me a little more push,” Olivieri said. “(The 400 record) has been my goal since missing it by 0.18 seconds last year. That .01 was tough, but I can’t be mad. It’s an amazing accomplishment for me.”

Frankfort trackOlivieri’s teammate, Anna Plum, came away with the championship in the 300 hurdles with a personal-record time of 47.03.

Frankfort finished third on the day with 39 points, thanks largely to senior Tara Townsend.

Townsend collected her third pole vault state title with a leap of 11-6. She attempted to set an LPD4 Finals record of 12-1, but just couldn’t quite get over the bar.

“It was a little disappointing because I went 12 last year and I wanted to go higher, but I can’t really be too disappointed,” Townsend said of her vault performance. “I just took a deep breath on the last one and gave all I had.”

Townsend followed up her pole vault title by winning the 100 dash championship in a time of 12.79. She also was the anchor leg of the winning 400-meter relay team (51.87), while placing third in the 200 dash. Not bad while dealing with a hamstring injury in the process.

Buckley sophomore Aiden Harrand had an impressive day, as she took home titles in the 800 and 1,600 runs. In the 800, Harrand had a PR of 2:19.25, while she finished the 1,600 in a PR of 4:56.38.

Fowler won the 1,600-meter relay with a time of 4:10.11 to close out the meet. The Eagles came in fourth as a team with 35 points. Rochester Hills Lutheran Northwest won the 3,200 relay with a time of 9:59.16.

Brynn Mericle won the 100 hurdles with a PR time of 15.93 to spark East Jackson to a fifth-place finish as a team.

In the field events, Morrice senior Emma Valentine repeated as the LPD4 high jump champion with a leap of 5-6.

“It was very nerve-wracking, because I wanted to repeat but I wasn’t sure how the day would pan out,” Valentine said. “I was very excited to be able to clear (5-6) again. It was great to be able to show up and perform well.”

Hillsdale Academy’s Anna Roberts took home the long jump title with a jump of 16-5.5. Gobles’ Elli Stender won the discus with a PR toss of 122-9. Kalamazoo Christian’s Tess VanDyk repeated as champion of the shot put with a throw of 41-7.
