ESPN: Koivun Claims 3M Open Title in Third Pro Start, Fending Off Scheffler's Surge

A Historic Debut Win for a 21-Year-Old

Jackson Koivun delivered one of the most remarkable professional debuts in recent PGA Tour memory, capturing the 3M Open in just his third career start as a pro. His closing 5-under 66 produced a tournament-record 25-under 259 total, securing a 3-shot victory over world No. 1 Scottie Scheffler.

Holding Off the World's Best

Scheffler mounted a serious challenge with a final-round 63, but Koivun never buckled. He went bogey-free for the second consecutive day, with a clutch par-saving putt on the 9th hole proving pivotal. "All throughout the crowd I kept hearing, 'Scottie's coming,'" Koivun said. "I just tried to tune that out." Scheffler settled for his fifth runner-up finish of the season.

Matsuyama Hideki, Brian Harman, Chandler Phillips, and Denny McCarthy tied for third at 20-under.

A Foundation Built on Process

A former Auburn standout who broke the NCAA career stroke average record (68.89 per round), Koivun became the fourth rookie winner of the PGA Tour season. The victory earned him $1,584,000 and vaulted him 124 spots in the FedEx Cup standings to 70th—just inside the playoff cutline with two regular-season events remaining.

Strokeslab Perspective

While full SG breakdowns are pending, Koivun's bogey-free final two rounds and a blistering third-round 61 strongly suggest elite SG: APP and SG: Putting performance. His self-described "superpower"—strategic thinking under pressure—aligns precisely with what separates one-time winners from consistent performers on tour.
