American rookie Jackson Koivun held his nerve to claim his first PGA Tour win at the 3M Open on Sunday, beating Scottie Scheffler by three strokes, Yankee Scores reports.
In only his third tournament as a professional, Koivun charged to a three-shot lead Saturday with a 10-under 61.
The 21-year-old then extended his advantage to five in the final round at TPC Twin Cities in Minnesota, before world number one Scheffler put him under pressure.
The crowd reminded Jackson Koivun all day that “Scottie’s comin’ … Scottie’s comin.'”

The four-time major champion started the back nine with three consecutive birdies and then picked up two more over the final three holes to finish with an eight-under 63 and trail compatriot Koivun by two shots.
Koivun, a former world amateur number one, could have wobbled at that point with holes to play, but instead he made his fifth birdie of the day at 16 before wrapping up a five-under 66 to finish on 25 under par overall.
“I had some nerves coming down 18,” said Koivun. “All throughout the crowd I kept hearing ‘Scottie’s coming, Scottie’s coming’.
“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.”
American trio Denny McCarthy, Brian Harman and Chandler Phillips were five strokes behind Koivun tied for third with Japan’s Hideki Matsuyama.
Michael Kim shot a 12-under 59 on Friday, but the American ended up tied for 10th after closing with rounds of 70 and 69.
