At TPC Twin Cities in Blaine, Minnesota, Jackson Koivun turned in a record-breaking performance to win the 2026 3M Open, reaching 25 under par (259) to break the tournament scoring record and finish three shots ahead of Scottie Scheffler. It was Koivun's first PGA Tour victory, earned in only his third professional start. The same week produced one of golf's rarest feats when Michael Kim shot a second-round 59 — only the 15th sub-60 round in PGA Tour history.
