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.”

Tie Nets P-W Girls Repeat, Grass Lake's 1st Title Since 1978

JENISON — Grass Lake coach Anthony Cole and Pewamo-Westphalia mentor Scott Werner had a dilemma after their teams tied for the Lower Peninsula Division 3 team championship Saturday.

It boiled down to this: Co-champions, but only one trophy available.

They settled it in a classic fashion: Rock, Paper, Scissors.

Even though there was a bit of orientation, first “We had to figure out how to do it,” Werner said. “We had to get into sync first, and it came down to best two out of three. And, fittingly, it came down to the last one.”

In this case, Werner’s paper covered Cole’s rock, and the Pirates went home with the trophy.

It was about the only disappointment the Grass Lake team suffered on the day as the Warriors also won the boys title.

Pewamo-Westphalia led most of Saturday, but the Warriors forged the tie when its 1,600 relay team, anchored by Lexie Bargesser, finished second in that event.

Byron track & fieldIt was Grass Lake’s first MHSAA title in girls track & field since winning back-to-back Class D championships in 1977 and 1978, while it was the second in a row for the Pirates, who won the team title in 2019.

“We’re so happy to be back,” Werner said. “We had a team we thought was good enough to win it last year, too.”

It was the fifth girls title overall for Pewamo-Westphalia, which has finished first or second at five of the last eight Division 3 state meets.

“We like being on that podium,” Werner said, grinning.

Depth played a role for the Pirates.

Senior Sophie Thelen finished third in the 100, second in the 200, third in the pole vault and was on the 800 relay that finished fourth. Freshman Saige Martin had a big day, taking second in the 100 hurdles and third in the 300 hurdles.

“We also scored in some relays,” Werner said. “It was all over the board. Everyone stepped up."

Cole was pleased and a little surprised by his team’s performance.

“If you had told me (Friday) that we would do this today and our kids would perform the way they did, I would have probably laughed,” Cole said. “It was a nice surprise. We knew it would be close. The girls took care of business all day, and sure enough, we were there. Co-champs isn’t bad."

The Warriors were happy to share, and Bargesser played a key role Saturday, winning the 100, 200, and the 400 (in record time) while also anchoring the 1,600 relay that finished second.

Kailee Sandoval also had a big day,

“She ran an outstanding 800 in this heat, and ran a great leg to start the 4x400 relay,” Cole said. “She ran her butt off. It was her senior meet, and she left it all out there. I’m so happy for her.”

Byron finished third on the strength of record-setting performances by senior Sarah Marvin and a strong performance by fraternal twin Becky, both in the throwing events.

Sarah Marvin set a Lower Peninsula Division 3 mark in the discus at 160 feet even and set an all-Finals record in the shot put with a throw of 50 feet, 9½ inches, making her the first high school girl in Michigan to throw for 50 or more feet at the state meet. She missed setting an all-meet record in the discus by 3 feet, 9 inches.

“I would have liked to have broken the MHSAA record,” she said. “But I’m so happy to have (the Division 3) record.”

She was just as happy for her sister, who had personal bests in the shot and discus.

“She wanted a second (place) and a second, but all you can do is be better than yourself, and she did that in both events,” Sarah Marvin said of her twin. “I think it was a fantastic day for her.”

It also was a fantastic day for Ithaca junior Lani Bloom, who won the 800 in 2:13.67 and the 1,600 in a meet record 4:48.89. Mason County Central's Nyah Tyron swept the hurdles races with a 15.36 in the 100 and 45.01 in the 300.

But as for regrets, Cole had one on what was a pretty good day for his team.

“I’m pretty hyper-competitive,” he said, grinning. “I should not have thrown rock that third time. I’m usually a scissors guy, but I went rock and (Werner) threw paper for the third time. I just couldn’t believe it.”

And then he joined his team, beaming at their accomplishment.
