Jackson Koivun clinched the 3M Open title at TPC Twin Cities in Minnesota on Sunday, July 26, 2026, finishing 25-under par to win by three strokes over world number one Scottie Scheffler [1, 2, 3, 4, 5]. The 21-year-old posted a bogey-free 66 in the final round to seal his victory [1, 2, 4].
Koivun set a tournament record in round three with a 10-under 61, including a back nine 28 — the lowest back nine score ever recorded at the 3M Open [1, 6, 4]. He entered the final day with a three-shot lead after that round [1, 6, 4].
Scheffler shot a strong 8-under 63 in the final round but could not close the gap [1, 2, 3, 4, 5]. Koivun said he managed the crowd pressure well despite fans chanting "Scottie's coming," focusing on executing his game: "I just tried to tune that out and keep playing the golf I knew I could and was able to find some good putts coming down the stretch" [1].
Koivun has played only three professional PGA Tour events, turning pro after finishing tied for 23rd at the 2026 U.S. Open [2, 6, 3, 4, 5]. He earned his PGA Tour card through the PGA Tour University accelerated program, foregoing his senior college season [6, 3, 5]. Prior to turning professional, he was the top-ranked amateur golfer in the world [1, 5].
Other notable finishers include Denny McCarthy, Brian Harman, Chandler Phillips, and Hideki Matsuyama, who tied for third place at 20-under par [1, 2, 3]. Michael Kim shot a 12-under 59 in the second round but ended the tournament tied for 10th after rounds of 70 and 69 [1, 6].
Koivun earned $1.584 million as the tournament winner [4]. Reflecting on his breakthrough win, he said, "I just love this game. I love golf, it’s everything I do. I have a tough time getting away from it… It’s been love at first sight" [4].
The 3M Open concluded after four rounds on July 26, wrapping up Koivun’s rapid rise just 24 days after turning professional [1, 2, 4].
