Koivun wins 3M Open in third pro start, holding off Scheffler

Jackson Koivun secured his first career PGA Tour victory this weekend at the 3M Open, marking an impressive milestone in only his third start as a professional. The 21-year-old talent finished with a tournament-record score of 25-under 259 at TPC Twin Cities, successfully holding off a late charge from the world's top-ranked player, Scottie Scheffler.

Scheffler mounted significant pressure throughout the final round, posting a 63, but he ultimately finished three strokes behind the rookie. Koivun maintained composure during the 97-degree heat in Blaine, Minnesota, remaining bogey-free throughout his final round. His performance was highlighted by a crucial par-saving putt on the ninth hole, which preserved his momentum as he moved into the back nine.

The victory carries major implications for the remainder of the season. With the win, Koivun collected $1.584 million and climbed 124 spots in the FedEx Cup standings, moving into 70th place. This jump puts him within striking distance of the playoffs as the regular season reaches its final two events.

Koivun joins a growing group of young players finding immediate success on the tour. Scheffler acknowledged the skill level of these recent college graduates, noting their preparation and mental strength in high-pressure environments. For Koivun, the win validates a steady rise that included an NCAA career stroke average record and a national championship with Auburn just last month.

This tournament result leaves Scheffler with his fifth runner-up finish of the season. Meanwhile, the group tied for third at 20-under included Hideki Matsuyama, Brian Harman, Chandler Phillips, and Denny McCarthy. The victory serves as a breakout moment for Koivun, who now pivots toward the postseason with newfound momentum.
