PGA Tour rookie Jackson Koivun shot a third-round 61 at the 3M Open in Blaine, Minnesota, taking a three-stroke lead at 20-under par while setting a tournament record with a 28 on the back nine at TPC Twin Cities, according to tournament reports. The 21-year-old former Auburn standout turned professional last month following the U.S. Open and separated from the field on a steamy Saturday afternoon with two eagles and six birdies.

Emiliano Grillo and Ben Kohles sit tied for second place at 17-under par after each carding a 65 in the third round. Michael Brennan shot a 63 to share fourth place at 16-under par alongside Chandler Phillips, while Denny McCarthy, Billy Horschel, and Michael Kim occupy sixth place at 15-under par. World number-one Scottie Scheffler carded a 64, finishing six strokes back in a four-way tie for ninth place alongside Davis Thompson, Seamus Power, and Brian Harman, according to official scoring data.
Did you know? Jackson Koivun became the youngest 54-hole leader on tour this season, tying the 54-hole record of 193 set by 2023 champion Lee Hodges.
Koivun Relies on Collegiate Experience Under Pressure
Koivun sank a 12-foot putt on the 12th green and a 14-footer on the 18th to eagle two of the course’s three par-5s, positioning himself for a final-round test on the lake-filled layout. “Just got to keep the foot on the gas,” Koivun said regarding his strategy heading into Sunday. Having tied for 10th two weeks prior at the ISCO Championship in Kentucky, Koivun credited his amateur career for his composure. “Playing at Auburn was so much fun. We were definitely put in some stressful situations at national championships and just collegiate play,” Koivun stated. “I’m just trying to lean on those experiences.”
Veteran Contenders and Crowd Reactions in Minnesota
Ben Kohles, who held the first-round lead after shooting a 62, played a bogey-free round in pursuit of his first tour victory. Meanwhile, 33-year-old Emiliano Grillo eagled the 18th hole to compensate for earlier missed putts on the greens. “These kids are playing better every day,” Grillo said. “It’s hard to keep up with them. I’ve just got to go and shoot my lowest.” Scottie Scheffler drew large galleries packed deep along the ropes, electrifying fans by sinking a 55-foot eagle putt on the par-4 16th hole. “The support this week’s been tremendous,” Scheffler noted.

Pro Tip: When tracking late-summer PGA Tour events at TPC Twin Cities, keep a close eye on players capitalizing on the par-5s, as the lake-laden course rewards aggressive second shots on holes like the 18th.

Boost its search engine visibility with relevant keywords for maximum impact. Immunotherapy resistance remains one of the biggest hurdles in cancer treatment. According to a recent study published in the journal Nature Communications, scientists at the Salk Institute have made a groundbreaking discovery that sheds light on the underlying mechanisms behind this resistance. The study reveals that interferons, a type of protein that plays a crucial role in the immune system, can contribute to mitochondrial dysfunction in cancer cells. This dysfunction can lead to the production of prostaglandin E2 (PGE2), a molecule that promotes tumor growth and resistance to immunotherapy. In their study, the researchers found that PGE2 production was a key factor in the development of immunotherapy resistance in cancer cells. The team used a combination of experimental and computational models to investigate the relationship between interferons, mitochondrial dysfunction, and PGE2 production. The findings of the study suggest that targeting PGE2 production could be a potential strategy for overcoming immunotherapy resistance. The researchers propose that blocking PGE2 receptors or inhibiting its production could help restore the function of mitochondria in cancer cells, making them more susceptible to immunotherapy. The study’s authors hope that their findings will pave the way for the development of new therapies that can overcome immunotherapy resistance and improve treatment outcomes for cancer patients.
