A pitching laboratory helped this 16-year-old throw 101.7 mph. But he’s ‘not just a baseball player.’

Cole Kuhn is one of the nation’s top high school pitchers with a scholarship to Duke and attention from major league scouts. And it all happened about as fast as the 6-foot-6 righty throws.

Andrew Kuhn dropped the final score of Ancillae-Assumpta Academy’s seventh- and eighth-grade basketball game into the family group chat last month. He wanted to make sure his 16-year-old son Cole knew that 13-year-old Gavin played well.

The older son responded with an update of his own: a video of him throwing a 101.7-mph fastball.

“New Year’s resolution,” Cole Kuhn texted the family.

Kuhn went to St. Joseph’s Prep on a partial music scholarship — he has played the double bass since the fourth grade — and failed to make the JV baseball team as a freshman. Now he was showing his family that he could throw a fastball harder than most major leaguers.

The teenager from Elkins Park is one of the nation’s top high school pitchers with a scholarship to Duke University and is already being scouted for the 2027 Major League Baseball draft. And it all happened so rapidly; about as fast as the pitches the 6-foot-6 teenager fires from his right hand.

Kuhn was throwing 90 mph in January 2025 when he enrolled at Ascent Athlete, a training center in Garnet Valley that looks like a baseball laboratory. High-tech cameras measure Kuhn’s movements on the mound, a team of coaches studies his mechanics, and he learns in real time how many RPMs his fastball registers. Big league players work out in the morning before high schoolers filter in in the afternoon.

A fitness center upstairs is focused on plyometrics and a computer connected to the batting cages allows a hitter to see how his swings would fare in a big-league park. A dry-erase board near the entrance lists the fastest pitches thrown at Ascent divided into three categories: pro, college, and high school.

“Where do you stack up?” the board says.

Kuhn, first in the high school column by more than 5 mph, has the fastest pitch.

The facility is open six days a week and Kuhn is there nearly every day, often finding someone on Sundays to unlock the door when the lab is closed. His 101.7-mph fastball did not happen by accident.

“Without question, that place is the single biggest driving force behind his major jumps over the last eight months,” said Kuhn’s mother, Tonya Lawrence. “They’re comprehensive, they’re involved, and they know what they’re doing.”

Scott Lawler, the general manager of Ascent, called Kuhn “a unicorn.” Lawler, who played at Bishop Kenrick High in the 1990s, has never seen a high school arm like this. There is no denying the promise of Kuhn’s right arm, but he is also just a kid who does not yet have a driver’s license.

Andrew Kuhn picked his son up from a friend’s house after Cole threw that 101.7-mph fastball and shook his hand. Two years earlier, Kuhn was nervous to tell his father that he wanted to play winter baseball instead of freshman basketball at the Prep. His parents played college hoops and he thought he’d disappoint them if he didn’t play.

This was not their journey, Andrew told him. This was Cole’s. The son has led the way ever since as he charted his path to that fastball. Dad was proud.

“I said good job,” Andrewsaid. “Then that was about it. Then it’s get home, walk the dogs, have dinner. You’re not all that. You still have chores. Who knows? This whole thing might fall apart at some point. You have to be prepared. You’re not just a baseball player.”

Ballet to baseball

The letter in Cole Kuhn’s folder as a second grader at Myers Elementary School advertised a ballet class for boys in Jenkintown.

“He was always the kind of kid who if you said, ‘Do you want to try this?’ He would say, ‘Sure,’” Tonya said.

So they signed their son up for ballet at the Metropolitan Ballet Academy where the teachers were strict and timeliness was prudent.

“Six years later, it was clear that he benefited from it,” Tonya said. “Discipline, core strength, grace under pressure. This studio was serious. It was the real deal and we didn’t know that. It just came home in the afternoon packet.”

Kuhn started playing the piano in kindergarten, picked up the double bass in elementary school, and took six years of ballet. He played baseball in the spring, swam in the summer at a public pool, played soccer in the fall and basketball in the winter.

“We tried to get our kids to do everything and then decide what sticks,” Tonya said. “We believe that variety is good for the brain and the body and the mind.”

Andrew and Tonya never intended to build a baseball prodigy. But perhaps keeping him well-rounded — from ballet to baseball — helped Kuhn blossom into the pitcher he is now. He was 15 years old when his fastball reached 90 mph and Tonya said that moment was like an “epiphany” for her son. He now believed he could do this. Kuhn told his parents he wanted to focus solely on baseball.

“It’s not like we’ve been pushing him or somehow training him to hit 90 mph. It wasn’t even on our radar. It just happened,” Andrew said. “In the big picture, it’s really about exercise, friendship, and competition. Then, who knows? Hopefully it’s intriguing enough and interesting enough that kids want to stick with it. We want our kids to be well-rounded and respectful and to try their best.”

Charting his path

Kuhn told his father last year that he wanted to train at Ascent after meeting Lawler at an event. Many of Kuhn’s Prep teammates were already there and the pitcher thought it was where he needed to be.

Lawler played minor-league ball and coached in college. Jeff Randazzo, Ascent’s owner, was a star at Cardinal O’Hara and is now an agent for major league ballplayers. They have a glistening facility and the connections a player needs to reach the next level.

“This whole world ties together between how you train, who you play for, and who you play in front of,” Lawler said.

Andrew said OK but told his son that he would have to inform his coach in Ambler that he was leaving.

“Ambler did so much for him so you can’t just send a text that you’re leaving,” Andrew said.

So Andrew stood with his son after the team’s final practice and listened to Cole break the news. Andrew played basketball at Franklin & Marshall and Tonya played hoops and lacrosse at Yale before playing basketball professionally overseas. They want their son to make his own decisions, which means working up the courage to explain to someone why you’re leaving.

“That was taking responsibility for the choices you’re making,” Andrew said. “He did it face-to-face. It was hard and emotional for him to leave, but he knew in his own mind that that was the path for him. Cole told him, ‘My dream is to get to MLB and I think the best path for me to get there is to switch to Ascent.’ I was like, ‘Oh, Cole. You sure you want to say all that to this?’”

Kuhn was paired at Ascent with David Keller, the facility’s director of pitching development. Keller pitched at Lock Haven University, where he delved into the data-driven methods that have overtaken baseball since the early 2000s. He put Kuhn on a throwing program and told him that his work upstairs in the weight room was just as important.

Kuhn gets a ride after school to Ascent from Prep senior Mihretu Rupertus — “I tell him, ‘You treat that dude to anything he wants at Wawa,’” Tonya said — and is given a checklist of exercises to do. He gained 35 pounds from working at Ascent, filling out his towering frame.

Kuhn’s fastball took off as he hit 95 mph last July at an event in Georgia. He pitched six innings, showing he could do more than just light up radar guns. The college coaches watching took notice. The pitcher who studied ballet was suddenly a can’t-miss prospect.

“That was for me when I said, ‘This kid is going to be really, really good,’” Lawler said.

Facing adversity

Kuhn’s phone buzzed exactly at midnight last summer when college coaches were first allowed to contact him. First was Miami. Then Texas Tech. More than 30 schools called that day. A few months earlier, Kuhn was hoping to play college ball at a small school with strong academics. Now the big programs were chasing him. It was a whirlwind.

He flew the next weekend with Tonya to California for the Area Code Games, a premier showcase event for the nation’s top players. It was Kuhn’s chance to show how special his arm was.

“He couldn’t get out of the first inning,” said Andrew, who watched from home on a livestream.

Kuhn, pitching in perhaps the biggest event of his career, struggled. The same coaches who contacted him days earlier were now backing off. Tonya told him afterward to forget about them.

“My line of work may be particularly suited to what was happening, but I am his mom,” said Tonya, who is a child psychiatrist. “It’s hard to watch, but it’s so much part of the game and part of life. I appreciate that that’s what happened. Maybe not at that moment, because seeing your kid struggle is hard. But I knew he was going to be fine. If people see an outing and say they’re no longer going to be behind the kid, then I don’t want my kid playing for that program. That was easy for me. In a weird way, I’m glad it happened. Not only for mental toughness but to kind of weed out people.”

Kuhn returned home, took a few days off, and then returned to Ascent. He kept working. There are going to be some bad days, his father reminded him.

“I always tell him that I’m happy for him when things go well,” Andrew said. “But really I’m only proud of the work that he does on a weekly basis. And because he’s such a grinder, it’s going to work out. And if it doesn’t at some point? Yeah, you can pivot. He has battled through tough things along the way.”

Staying healthy

They didn’t measure launch angles or even know how hard an opposing pitcher was throwing when Lawler was playing at Kenrick.

“It was ‘I hit the ball hard. Everyone is swinging and missing against this guy who looks like he’s throwing hard,’” Lawler said. “But we didn’t know how hard it was or how far it went.”

The new ways of instruction are great, Lawler said, as the real-time information provides instant feedback and allows for coaches and players to make corrections in the moment. He can study the movement on Kuhn’s fastball and tell the catcher where to keep his glove. But there’s also a need to manage the information that players see.

“We have to train the kids to not obsess over it,” Lawler said.

Kuhn said he likes to know how many RPMs his fastball has so he knows if he’s generating enough spin on his pitches. But he doesn’t chase the numbers. On the day he threw 101.7, Kuhn was actually working on developing a cutter. The triple-digit fastball just happened. On the mound, he said, he’s focused on the batter and not the data.

“It’s mental,” Kuhn said.

Major league evaluators — including Phillies general manager Preston Mattingly — came to Ascent last month to watch Kuhn pitch. Kuhn said it was exciting but the attention didn’t faze him. He’s committed to Duke, but things could change before he’s eligible to be drafted in July 2027. He’ll likely have a choice to make: Go to college or turn pro. First, he has to stay healthy.

“I don’t want him to feel like he has this golden arm and that’s the only thing that matters,” Andrew said. “But it is concerning. The whole thing about how many Tommy John surgeries there are and using the technology input to throw faster and faster, it’s a little worrisome. But it’s just, ‘Slow down.’”

Randazzo said it was no surprise that Kuhn hit triple digits as he has the frame (6-6 and 230 pounds) and arm speed to do so. But it was a slight surprise that it all came together nearly two years before he could get drafted. Now what?

“It’s very common these days with Tommy John surgery and injury in general,” Randazzo said. “You do have to find that balance with still being a normal 16-year-old kid. You want to tread lightly with it, but you also don’t want to put him into a bubble. You just have to be methodical about it with arm care and rest. It’s not a carnival game that this kid is throwing hard. It’s real. There’s no crystal ball with it.”

Kuhn’s fastball has spiked at Ascent, but he said the facility does not simply try to build velocity. The pitcher said it’s instead a result of everything else. He has a nutritionist, follows a workout regimen, and is already built like a major leaguer. The facility limits how often he can throw, knowing that overextending him as a teenager could hurt him in the future.

“You can never 100% prevent injury or setbacks,” Keller said. “But it is important that every day, everything we do contributes to his long-term health. We track all his volume, his intensity, his velocity, and how many times he throws. We want him to get to where he wants to be as safely as possible while also challenging him.”

Big-league dreams

A few days after Kuhn hit 101.7 mph, he marveled to his father how his fastball was nearly as fast as pitches thrown by Phillies closer Jhoan Duran.

“Yeah, it’s cool,” Andrew said. “But it’s not just a carnival trick. You have to make sure you’re doing everything to stay healthy.”

Three years ago, Kuhn failed to make the JV baseball team. And now he’s able to compare himself to big leaguers. It all happened so fast. He’ll pitch this spring for St. Joe’s Prep and spend the summer playing with Ascent’s travel team. The attention, Kuhn said, has been fun.

“This is like the best part of my life, honestly,” Kuhn said. “It’s only up from here. I’m really excited.”

In just a few years, he could be pitching in the majors. Maybe they’ll even turn the lights off like they do for Duran when Kuhn comes to the mound with a triple-digit fastball. It’s easy to imagine it all when you’re throwing 101.7 mph. First, he has to get his driver’s license. And that will be something he can text the family group chat about.

“He has a lot of supporting characters helping him get to where he’s hoping to go,” Tonya said. “For many boys in the world, it’s MLB, the NBA, or the NFL. I can’t even believe that this might happen. I’m still in awe. I continue to just be incredibly proud of the kinds of things that he’s doing and setting goals and reaching them left and right.”
