Rookie stuns 3M Open field with brutal 61 and record-setting back nine

Date:

A Rookie Makes History in Minnesota

Jackson Koivun has absolutely taken the PGA Tour by storm at the 3M Open. The 21-year-old rookie didn’t just play; he fired a stunning 61 in the third round to grab a three-stroke lead. He now sits at 20-under par at TPC Twin Cities, a number that screams dominance. This performance marks a massive breakthrough for the former top-ranked amateur. According to ESPN Golf, Koivun’s round included two eagles and six birdies. He set a new tournament record with a 28 on the back nine. That’s the kind of score that forces the field to wake up. This score has put him in a commanding position heading into the final day.

The field is chasing hard, but Koivun holds a distinct advantage. Emiliano Grillo and Ben Kohles share second place at 17 under after shooting 65s. Michael Brennan and Chandler Phillips sit in fourth at 16 under. The leaderboard remains tight behind the leader, yet Koivun’s momentum is undeniable. His rise from a college standout to a tour leader in just weeks is remarkable. ESPN Golf reported that he turned professional last month following the U.S. Open. Last month? That’s a fast track to the front.

The Details of a Historic Round

Koivun’s path to the lead was built on aggressive play and precise putting. He shot a 64 on Thursday and a 68 on Friday before his Saturday explosion. The 61 included eagles on two of the three par-5s on the lake-filled course. ESPN Golf noted he sank a 12-foot putt on the 12th green and a 14-footer on the 18th to secure those birdie opportunities. Those specific distances matter when you’re trying to post a record. The back nine of 28 was the key differentiator. It set a new standard for the event at TPC Twin Cities.

His previous form suggested he was ready for this moment. Koivun tied for 10th just two weeks ago at the ISCO Championship in Kentucky. That experience likely helped him handle the pressure. He navigated the course with confidence, capitalizing on every opportunity. The TPC Twin Cities course joined the tour schedule in 2019, making this record even more significant for the venue. Koivun’s ability to birdie and eagle in bunches separates him from the rest of the pack. Can anyone else match that kind of firepower?

Why This Performance Stands Out

The golf world rarely sees a rookie take such a dominant lead so quickly. Koivun’s background as the top-ranked amateur at Auburn prepared him for this stage. His transition to the pros has been seamless. While other players struggle to find their rhythm, Koivun is clicking on all cylinders. The three-stroke cushion gives him a psychological edge. It forces competitors to play catch-up, which often leads to mistakes. That’s the danger of trailing by that margin.

His putting display was particularly impressive. He didn’t just make putts; he made the difficult ones under pressure. The eagles on the par-5s showed his power and course management. He attacked pins and trusted his short game. This approach is essential for winning on a challenging layout like TPC Twin Cities. Koivun proved he can handle the pressure of a Sunday leaderboard. He has the skills to convert this lead into a trophy. Why would anyone bet against him now?

What to Watch in the Final Round

Koivun faces a tough challenge on Sunday. Grillo and Kohles will try to close the gap with aggressive play. The wind and course conditions could play a major role in the final outcome. Fans should watch how Koivun manages the pressure of leading. His previous rounds show he can handle stress well. If he maintains his current form, a victory seems likely. The PGA Tour has a new star on the horizon. One thing is for sure: the eyes of the tour are locked on him.

The rest of the field, including Denny McCarthy and Billy Horschel, will need perfect rounds to catch him. They are currently three strokes back at 15 under. Scottie Scheffler sits nine shots back, but anything can happen on the final day. Koivun has the momentum and the score to win. This tournament could define his rookie season. Everyone will be watching to see if he can close it out. Will he finish what he started?
