Jackson Koivun, a 21-year-old PGA Tour rookie and former Auburn standout, won the 3M Open in Blaine, Minnesota, by three strokes over world No. 1 Scottie Scheffler, finishing at 25-under and setting a 72-hole scoring record. He closed with a 66 in the final round after a 61 in the third round that featured a back-nine record 28.

The victory marks a notable early transition from amateur to pro, signaling Koivun's emergence as a rising star on the PGA Tour.
