Rapid Rise from Public Courses
Jackson Koivun made history by hoisting his first trophy less than a month into his professional career. This feat is remarkable given it occurred during only his third professional start. He won the 3M Open with a tournament-record score of 25-under. That performance allowed him to hold off Scottie Scheffler by three shots. It’s a stunning debut for a player who grew up on public courses in the San Jose, California, area. Santa Teresa Golf Club and Cinnabar Hills Golf Club were where his journey started. Youth On Course, a non-profit enabling junior golfers to play rounds for $5 or less (a massive help for any family), supported Koivun. This background gave him a unique perspective on the game long before he turned pro.
His path wasn’t a straight line to the top. Following pandemic disruptions during his first three high school years at Archbishop Mitty, Koivun relocated to Chapel Hill, North Carolina. To back his game, his parents George and Meghan moved the family just before his final high school year. Scholarship secured at Auburn, Koivun achieved immediate success there. According to MyGolfSpy Feedburner, he now aims to qualify for the U.S. Presidents Cup team this fall. Koivun told Clinard he intends to make the 2026 Presidents Cup, an event scheduled for that weekend. Can a rookie really pull that off? His stats say yes.
A Three-Model Iron Setup
While his win was impressive, the equipment Koivun uses is equally fascinating to watch. He doesn’t just play a combo set. He employs three distinct Titleist iron models, swapping shaft materials in his longest iron. This is a level of customization that few amateurs or even pros attempt. A Graphite Design Tour AD DI HY 95 X graphite shaft powers his 3-iron, a Titleist T250. Koivun’s 4-iron is a Titleist T100 with a Project X 6.5 steel shaft. His 5-iron through 9-iron consist of Titleist 620 MB Prototype clubs equipped with Project X 6.5 steel shafts.
This is not the separate T250·U utility iron. He pairs the regular T250 head with a graphite shaft. The T250 provides enhanced speed, height, and forgiveness for that longest iron. From there, the T100 4-iron acts as the bridge. More compact than the T250 yet offering slightly more assistance than the 620 MB Prototype Koivun uses from the 5-iron down, this club remains distinct. This setup shows a player who understands exactly how he needs the ball to fly at different distances. He also uses a Titleist GT2 driver at 8 degrees with a Fujikura Speeder 661 TR X shaft. His 3-wood is a Titleist GTS3 Prototype at 15 degrees with a Graphite Design Tour AD DI 8 X shaft. Every detail is tuned for maximum performance. Most guys would just grab a set and go, but Koivun’s dialing in his specs down to the gram.
Koivun’s win signals a shift in how young players approach the game. They use data and specific equipment choices to find an edge rather than relying on raw power alone. The fact that he won in his third start suggests he was ready long before the PGA Tour noticed him. His background on public courses likely taught him how to manage different conditions and course setups. That experience translates well to the pressure of a major tournament. The move to North Carolina for his final high school year was a bold step that paid off with an Auburn scholarship.
His ambition is clear and specific. He wants to make the Presidents Cup team. This is a high bar for a rookie, but his record suggests he can get there. The unique iron setup shows he is willing to do the work to find the perfect combination. Knowing exactly what each club does for him matters more than just having the best clubs. This attention to detail is what separates good players from great ones. He has a fifth gear that he can access when it matters most.
Next Steps on the Schedule
Koivun’s focus now turns to the upcoming season and the goal of qualifying for the U.S. Presidents Cup team. The event takes place in the fall of 2026. According to MyGolfSpy Feedburner, he has already informed his team of this specific target. Fans will be watching closely to see if he can maintain this momentum. The path to the Presidents Cup requires consistent play over several months. His win at the 3M Open proves he has the skill to compete at the highest level. The next concrete step is to perform well in the remaining tournaments this season to secure his spot on the team roster.
