2026 3M Open Final Round Preview: Koivun Leads by Three Heading Into Sunday

Lead: 21-Year-Old Pro Leads by Three

Jackson Koivun, a 21-year-old in just his third PGA Tour start as a professional, fired a stunning 10-under 61 on Saturday to seize a three-shot lead at the 2026 3M Open. He stands at 20-under par heading into Sunday's final round at TPC Twin Cities in Minnesota.

Who Is Koivun?

Koivun's rise is no fluke. At the 2026 U.S. Open — his final event as an amateur — he finished T23. Last week at the ISCO Championship, he recorded his first top-10 finish as a professional. Saturday's 61 suggests his trajectory is accelerating fast.

Strokeslab Take

Beyond the scoreboard, Koivun's rapid development from elite amateur to PGA Tour contender in three events is a case study worth tracking through a Strokes Gained lens — specifically whether his gains are being driven by approach play, putting, or both.
