The 2025 Pink Buckle Stallion Owners Select Sale in Guthrie, Oklahoma, saw excitement peak when Thee Ironman, a yearling stallion by Tres Seis and out of MJ Segers Fast Lane, brought a final bid of $260,000—making him the high seller of the day.
Representing buyer Sarah Miller, Brandon and Emily Cullins shared in the buzz at the Lazy E Arena alongside consignors Grant and Rayel Little, who raised and consigned the colt. The cross that produced Thee Ironman combines two of the most recognized names in barrel racing today: Tres Seis, a proven sire of champions, and MJ Segers Fast Lane, the $1.5 million-earning mare that carried Brandon Cullins to some of his career’s biggest wins.
“I never thought I’d get the opportunity to ride one like this,” Brandon said. “I’m just really glad it happened the way it did. He’s got everything you’d want in one—confident, built right, moves good, and the pedigree to back it up.”
An Exceptional Cross
For the Littles, the pairing of MJ Segers Fast Lane and Tres Seis was intentional and rooted in excellence. “When you breed exceptional to exceptional, you increase your odds of success,” said Grant Little. “This colt is one of one. We don’t have several stored up—he’s it. And we’re beyond grateful to see him go to such great people.”

The Littles purchased MJ Segers Fast Lane as a 2-year-old with just 60 days under saddle, recognizing her potential early. The mare went on to become one of the sport’s most celebrated money earners. “With a mare like that, you want to breed her to some of the best walking,” Grant added. “Tres Seis fit that perfectly, and this colt is everything we hoped for.”
Connections That Matter
Emily Cullins explained that the sale came together naturally after Miller reached out earlier in the year looking for a standout young prospect. “Sarah asked if we had anything we’d sell, and we just clicked with her,” Emily said. “When we talked about a horse we were really excited about, it was Thee Ironman. It’s kind of surreal that it worked out this way.”
When the hammer fell, Miller’s call confirmed the feeling shared by everyone involved: disbelief and excitement. “She said, ‘Did we really get him?’” Emily laughed. “None of us could believe it at first—we all had to double-check.”

A Sale with Heart
Beyond the sale itself, the Littles are using Thee Ironman’s success to make a difference. Two annual breedings to the colt will be dedicated to raising money for wounded and disabled veterans and Gold Star families.
Grant, a 27-year veteran of the Royal Canadian Mounted Police, including 16 years with a special forces team, said it’s his way of ensuring those who have served are not forgotten. “Whether it raises $500 or $50,000, I just want those people to know they’re remembered,” he said. “It’s important to us to give back.”
Looking Ahead
As Thee Ironman joins Miller’s program under Brandon and Emily Cullins, the group’s excitement is palpable. “There’s so much opportunity ahead,” Brandon said. “When you combine a horse like this with the Pink Buckle’s incentives, it’s hard not to get excited about what’s next.”
Grant Little echoed the sentiment: “When you start with good horses and good people, you increase your odds of success.”
From his flawless conformation to his unmatched pedigree, Thee Ironman represents more than just a high-selling colt—he’s a bridge between some of the most respected names in barrel racing and a testament to the kind of connections that make the Pink Buckle Sale one of the sport’s most meaningful events.
