3M Open: Rookie Jackson Koivun holds nerve to beat Scottie Scheffler for first PGA Tour win

Jackson Koivun secured his first professional victory at the 3M Open this weekend, defeating world number one Scottie Scheffler by three strokes. The 21-year-old rookie, who only turned professional two months ago, maintained a strong lead throughout the final round at TPC Twin Cities in Minnesota. Koivun finished at 25 under par, demonstrating significant composure under pressure.

Scheffler mounted a serious challenge during the back nine, firing an eight-under 63 to cut the deficit. The field heard constant reminders of the world number one's charge from the crowd, yet Koivun stayed consistent. He secured a birdie at the 16th hole to solidify his lead before concluding with a final round of 66. This win marks a major milestone for the former amateur star, who helped Auburn capture a college title earlier this year.

The tournament saw several other top performers in contention, with Denny McCarthy, Brian Harman, Chandler Phillips, and Hideki Matsuyama sharing third place. While Michael Kim grabbed headlines on Friday with a 12-under 59, he ultimately tied for 10th. Koivun's victory in only his third professional event highlights his rapid ascent in the sport.
