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.”

McBain Twins Geared Up for Last Finals
May 24, 2019

Special for Second Half
MCBAIN — It’s been said that records are made to be broken.
McBain twins Keegan and Klaudia O’Malley seem to have taken that notion to heart.
The seniors’ names are all over the school record books for track & field as they wind down their standout careers. Klaudia holds the all-time marks for the 800 meters (2 minutes, 17 seconds), 1,600 (5:04), 3,200 (11:06) and as an integral part of the Ramblers’ 3,200 relay team (9:57), while Keegan broke a 42-year-old school record in the 3,200 earlier this season in a time of 9:33, shaving five seconds off what had been the longest-standing boys track & field record on the school’s board.
“They hold all those distance records,” said McBain boys track & field head coach Pat Maloney. “Going down in history, they’re going to be talked about. People will be compared to them for years to come.
“It’s a lot of hard work behind the scenes. People don’t see how many miles they put in year after year after year.”
The O’Malleys certainly come by their running prowess honestly. Their father, Tim, has been the cross country coach at Cadillac for the past 18 years and has spent the last seven years as an assistant track coach at McBain. Their mother, Tasha, coaches cross country at McBain. Both parents have been active in competitive running as well, with Tasha having competed in multiple Boston Marathons among myriad other races.
“Our life pretty much revolves around running — in a fun way, not in a bad way,” said Tim O’Malley. “My wife raced a lot. I would just take the kids and pace them in the 5Ks that they wanted to run. They seemed to like it.”
The O’Malley children – including Maggie, the twins’ younger sister by two years – didn’t know any differently than being immersed in a running lifestyle.
“I’ve grown up with running,” said Klaudia.
Tim O’Malley jokingly says Keegan and Klaudia’s running careers actually began with running as a form of babysitting. Even when they were as young as 7 years old, the O’Malley twins would tag along with their father to practice. They attended cross country camps with the team, would run right along with the group, and even get to compete in open races following meets.
“I loved it and his team was so supportive, so I just got into it,” said Keegan.
Not only did the twins enjoy running, but it became quickly apparent that they were good at it too. Really good, in fact. Keegan and Klaudia started establishing school records in elementary school, and that continued as they moved into middle school and then high school. No one was surprised to see them become dominant runners at the high school level, to say the least.
“They hold all those distance records,” said Maloney. “People have been waiting for them to shine, and they haven’t disappointed by any means.”
Klaudia is the four-time Highland Conference champion in the 800 and 1,600, and a three-time winner of the 3,200 — she didn’t run that event this year. She has qualified for the MHSAA Lower Peninsula Division 3 Finals four times in the 1,600, three times with the 3,200 relay team, and twice each in the 800, 3,200 and with the 1,600 relay, earning all-state honors a total of six times across four events. She is qualified for the Finals in the 800, 1,600, 1,600 relay and 3,200 relay this season. Three of the four school records she holds came as a result of breaking her own record-setting times.
“Last year I didn’t feel as confident, but this year I feel a lot stronger and a lot more confident with my running,” said Klaudia. “It’s sweet to show, just because I’m from a small school, you can still have a lot of talent.”
Keegan is a three-time league champion in the 3,200 and twice has won the 1,600 and ran with the winning 3,200 relay. He also has four Regional crowns to his credit — twice winning the 3,200. He is qualified for the Finals in the 1,600, 3,200 and with the 3,200 relay. He battled an injury a year ago but has seemed to make up for any lost time with a dynamic senior season. That includes shattering Ron Eising’s school record in the 3,200 that had been around since 1977 with a stunning performance at the Shepherd Invitational that eclipsed Keegan’s personal best by 16 seconds.
“It was kind of like a dream come true because the guy who had the record (Eising) is very supportive of me,” said Keegan. “He came to the track and mentored me. Told me he wanted me to beat it. He wanted me to take after him. I put in a lot of training in the offseason, and I was really surprised when I got it, but I knew I could do it. I wasn’t terribly close. It was kind of a big PR (personal record).”
The twins will complete their high school careers at the Lower Peninsula Division 3 Finals at Jenison High School, then are taking their talents to Grand Valley State University in the fall. They say they are close and relish the idea of heading in the same direction for the next chapter of their careers.
“At first I didn’t really want to (go to the same school),” said Klaudia. “But senior year got going, and we got running together again. Now I’m glad I chose the same college as him. I’ll have a buddy there right away and I can still watch him and cheer him on at meets.”
Maloney has seen the work Keegan and Klaudia put into running, and he’s witnessed the records fall. He will be watching keenly to see how the O’Malleys perform at the collegiate level.
“They’re going to do a great job representing McBain, their family and northern Michigan runners,” he said. “I think they’ll be right in the heat of things for the next four years.”
