Chris Roycroft
Some players leave a mark on the field. Others leave a lasting mark on an entire city. In 2025, Chris Roycroft becomes just the fourth player to be inducted into the Bismarck Larks Hall of Fame — and for him, it’s more than an honor. It’s a full-circle moment.
“It is truly an honor,” Chris said. “I will never forget Bismarck. It has a special place in my heart.”
Chris joins fellow Larks legends Jeff Lindgren, Matt Warkentin, and Wyatt Ulrich in Hall of Fame history — but his path to this moment is one built on grit, belief, and one unforgettable summer in North Dakota.
Back in 2017 and 2018, Chris took the mound for the Larks — a Division III pitcher with a dream, 18 bullpen appearances, and something to prove. Over 18 innings, he allowed just five earned runs, struck out 18 batters, and issued only five walks. But his biggest stat? Belief — in himself, and in what was possible.
“As a DIII guy, I was hindered because no one was looking at guys like me,” Chris told Larks CEO John Bollinger. “What the Larks allowed me to do was play against high-level DI talent. I needed to see where I stood and prove to myself that this is achievable — that I can do this.”
That spark turned into something real. On May 7, 2024, Chris made his Major League Baseball debut with the St. Louis Cardinals, becoming just the second Larks alum ever to reach the big leagues. He’s since bounced between St. Louis and their AAA affiliate, the Memphis Redbirds, and was most recently recalled by the Cardinals on June 9.
Even as he takes the mound in front of 40,000 fans, Chris still carries Bismarck with him.
“Aurora University got maybe 50 to 100 fans a game,” Chris said. “The energy in Bismarck was incredible. If I can bring joy to the Bismarck fans, and they can get joy out of what I’m doing, that’s just a match made in heaven right there.”
But Chris’ story isn’t just about strikeouts or stadiums. After college, he briefly stepped away from the game altogether. The road has been anything but smooth.
“It hasn’t always been easy. There were times I thought about stopping. Being done,” he said.
“You’ve got to keep going. Never give up.”
That’s the spirit of a Lark. That’s the magic of Bismarck. And that’s why Chris Roycroft will always be a part of this team — not just as a player, but as a reminder of what’s possible when talent, opportunity, and heart collide.
Welcome home, Hall of Famer.
