BLAINE, Minn. – On the 18th fairway at TPC Twin Cities, the gallery started calling it out. “Scottie’s coming,” they said, loud enough that Jackson Koivun could hear every word. Behind him, world No. 1 Scottie Scheffler had just posted a back-nine charge that had the Sunday leaderboard lurching.
Koivun, 21 years old and six weeks removed from the amateur ranks, heard them. He parred the 18th anyway.
By the time the scores were final, the 3M Open belonged to Koivun at 25-under par, a tournament record, three strokes clear of Scheffler, who closed with an 8-under 63 that would have won on almost any other Sunday this season. The victory, arriving in Koivun’s third professional start, was the kind that takes a few hours to register fully: not a fluke, not a gift from a weakened field, but a sustained four-day performance from someone who, until June, had never cashed a PGA Tour check.
Koivun turned professional after the U.S. Open in June. He missed the cut at the John Deere Classic in his debut, finished tied tenth at the Isco Championship in his second start, and arrived in Blaine with long odds and no particular expectations attached. Through four rounds at TPC Twin Cities, he made 24 birdies, two eagles, and only three bogeys, all of them bunched into the second round, the same round that another player nearly wrote into the record books for entirely different reasons.
Michael Kim shot a 59 on Friday. The round was the 16th sub-60 score in PGA Tour history, falling one short of Jim Furyk’s 58 from the 2016 Travelers Championship, according to Sky Sports. Kim’s scorecard was flawless: 12 birdies, no bogeys, and a 24-foot birdie putt on the 18th green that completed the round. He entered the weekend three shots clear at 14-under par and was clear-eyed about what was coming. “That guy named Scottie Scheffler is probably going to throw up a good score today anyway,” Kim said after the round.
He was right, and wrong. Scheffler closed in 63. Koivun closed in 66, and the three-shot gap held.
The question Koivun had to answer in the final round was not whether he could make birdies. His Saturday 61, bogey-free and built around two eagles and an eight-under back nine, had settled that. The question was whether he could hold his composure while Scheffler was making the leaderboard move. On the 16th hole Sunday, Sky Sports reported, Scheffler chipped in for eagle to tighten the margin. The gallery noise shifted. The chants reached the fairway.
“I played a great round of golf,” Koivun said. “I definitely had some nerves coming down 18. I heard the crowd saying, ‘Scottie’s coming, Scottie’s coming,’ but I just tried to blank that out.”
He blanked it out. The par on 18 was the last entry on a card that earned him $1.584 million from an $8.8 million total purse and 500 FedExCup points that rearranged his playoff standing entirely.
Koivun entered the week outside the top 190 in the FedExCup standings. He leaves it 70th, the last position that qualifies for the postseason, with two regular-season events remaining. The practical consequence is significant: Koivun, whose amateur ranking at the time of his U.S. Open appearance placed him No. 1 in the world, now has playoff eligibility and full event-selection flexibility through the end of the year. He carried that momentum directly to Detroit Golf Club for the Rocket Classic, where he arrived as the week’s central storyline.
Scheffler’s closing 63 was the kind of round that ordinarily forces a different outcome. He has not won since January’s American Express, and the pursuit at TPC Twin Cities had the shape of a correction in progress. What it produced instead was a runner-up finish behind a 21-year-old in his third professional event, a result that requires recognition even by golf’s recent standards for youth.
The tournament also produced one of the week’s quieter subplots. Muzzy Donohue, the Minnesota State Open winner, made the cut at TPC Twin Cities in his PGA Tour debut, weeks removed from competing in front of roughly 50 people. The state gave him a proper send-off.
Sky Sports analyst Simon Holmes described Koivun in the aftermath as “turbocharged and ready to perform immediately,” with the strongest aspects of his game being “his putting and his mindset.” Both held on Sunday. What remains untested is whether the steadiness Koivun showed while Scheffler’s eagle was drawing the crowd’s noise toward 18 is a defining characteristic or simply a temperature he has not yet had to maintain across a full season. The Rocket Classic is already presenting the next test, with Peter Malnati’s opening 61 in Detroit leading a field that has taken note of Koivun’s arrival.
“I love this game,” Koivun said, standing with the trophy at TPC Twin Cities. “It’s everything I do. It was love at first sight.”
