Jackson Koivun wins 3M Open in third pro start

Jackson Koivun won the 3M Open by three strokes at TPC Twin Cities in Blaine, Minnesota, holding off Scottie Scheffler in the final round and turning only his third professional start into a breakthrough that immediately raises the bar for his next one.

Koivun’s path to the trophy was built the day before, when he shot a third-round 61 and closed the round with a tournament-record 28 on the back nine. That score gave him a three-stroke lead entering Sunday and set up a final pairing that had already been framed as a showdown between a fast-rising newcomer and one of golf’s biggest names. Scheffler surged late and pressed Koivun hard, but Koivun kept his lead intact through the back nine and finished at the top of a crowded PGA Tour leaderboard.

The numbers behind the week show why the victory landed with such force. Koivun reached 24-under and tied the 3M Open scoring record with six holes left on Sunday, then converted that position into a three-shot win. Golf Channel noted that the 61 gave him his first career 54-hole lead on the PGA Tour, while CBS Sports tracked the scoring-record chase as Sunday unfolded. The result was less a surprise finish than a demonstration that Koivun could carry a lead against elite competition without tightening up.

That matters because Koivun arrived in Minnesota with a résumé already loaded for a player still just starting out as a pro. Auburn and USGA materials identified him as a rising Auburn golfer from Chapel Hill, North Carolina, who made the 2025 USA Walker Cup team and became the first freshman to win the Haskins Award. Golfweek also noted that his mother, Meghan Koivun, recalled a second-grade teacher moving him ahead in math because he had already mastered addition and subtraction, with Fred Garcia serving as his golf coach.

Koivun’s win fits the new pace of professional golf, where top young players are expected to contend almost immediately after turning pro. In a single week, he moved from promising rookie to tournament winner by surviving a Sunday chase from Scheffler, a result that gives him early world-ranking momentum, sharper expectations and a wider national profile before his career has even had time to settle.
