Jackson Koivun’s Saturday at the 3M Open wasn’t just good. It was historic. When he fired an eight-under 28 on the back nine at TPC Twin Cities, he didn’t just set a new tournament record; he flipped the leaderboard on its head. That electrifying stretch propelled the 21-year-old to a 20-under total, putting him firmly in the driver’s seat heading into Sunday’s final round.
This isn’t just a story about a hot round. It’s about a rising star transitioning from amateur dominance to professional promise. Koivun, in just his third professional start, has already proven he can compete with the best. He’s set to tee off alongside Emiliano Grillo with a three-shot lead, while Scottie Scheffler, who earlier posted a strong seven-under 64, lurks six shots back. The stakes? A first PGA Tour victory and a defining moment for a young career on the cusp.
Eight Under on the Back Nine: The Moment That Changed Everything
Imagine the pressure cooker of a PGA Tour event Saturday afternoon. Scottie Scheffler had just finished a scorching back nine himself, including a memorable chip-in eagle at the 16th hole, wrapping up a seven-under 64 that briefly created a seven-way tie for the lead. Then came Koivun’s response—an explosive eight-under 28 on the back nine that shattered expectations and tournament records.
Koivun’s back nine started with a birdie at the 9th hole, then another at 10. The real statement came on the 12th, where a 305-yard 3-wood found the middle of the green, setting up a 12-foot eagle putt that gave him the outright lead. Birdies followed on 13, 16, and 17, and he closed with a 14-footer for eagle on 18—two eagles in seven holes. The result: a 10-under 61 total that vaulted him to 20 under par.
From Amateur Ace to PGA Contender
Koivun’s rise is fast and striking. As the top-ranked amateur in the class of 2023, he made waves at Auburn University by capturing all four major collegiate golf awards, including the Phil Mickelson and Ben Hogan honors, twice winning the latter two. Turning pro only a couple of months ago, this 3M Open marks only his third professional start, yet he already boasts six top-25 finishes and three top-six placements in his brief PGA Tour career.
His steady climb and now this record-setting round suggest a player ready to break through. At just 21, Koivun is balancing youthful energy with a mature strategic approach—sticking to a game plan and keeping a calm mindset even as history unfolds around him.
Scottie Scheffler’s Challenge Looms Large
Scheffler’s back nine earlier Saturday was a statement in itself. Although he began the day seven shots off the lead, he birdied four holes after the turn and chipped in for eagle on the drivable par-4 16th, narrowly missing a back-nine record putt on 18 that would have matched Koivun’s feat.
“I kept myself in the tournament with a good back nine today,” Scheffler said. “Overall definitely pleased with the back nine, but probably going to need another low number tomorrow if I want to keep the pace.” His words underscore the challenge Koivun has set for the field: a high bar demanding another stellar round to stay within striking distance.
Why the Jackson Koivun 3M Open 2026 Moment Matters
What makes Koivun’s performance more than just a flashy round? It’s the timing and potential. Early in his pro career, he’s seizing a rare opportunity to claim a PGA Tour title and announce himself as a serious contender. The 3M Open’s format and course setup reward precision and smart aggression—qualities Koivun displayed in abundance on his back nine.
The tournament’s history has seen young players surge and falter under pressure. Koivun’s ability to not only surge but hold a lead heading into the final round speaks to a mental toughness that will be tested Sunday alongside Grillo and with Scheffler charging.
What to Watch for Sunday
The final round at the 3M Open promises a classic showdown. Koivun’s three-shot lead is comfortable but not insurmountable, especially with Scheffler six back and known for clutch finishes. Grillo, sharing the final pairing with Koivun, has been steady and poised as well.
Sunday will test who can manage pin placements, course conditions, and nerves best. For Koivun, the key will be sticking to his game plan and maintaining the composure that fueled his record-setting back nine. Will this young talent cap his breakthrough with a first PGA Tour win? The pressure will tell.
As All The Golf reported, this moment isn’t just about a leaderboard—it’s a potential turning point in a promising career and a reminder that the future of golf is arriving fast.
For fans tracking golf rankings, equipment choices, and course strategies, Koivun’s 3M Open performance is a case study in how precision and timing on the course can define a player’s trajectory.
