Rookie Jackson Koivun wins the 3M Open in his third PGA Tour start, claiming his first career title. Multiple outlets report that the American, 21, finishes at 25-under par and holds off a late charge from world No. 1 Scottie Scheffler. Koivun’s final margin is three strokes, with Scheffler closing with a 63 at TPC Twin Cities. The win is framed across sources as coming quickly after Koivun turns professional earlier in the summer and makes only a small number of PGA Tour appearances. Reports also note Koivun turned pro only after the U.S. Open and has played a limited schedule since, including the 3M Open in Blaine, Minnesota. Several outlets emphasize that Koivun does not falter in the closing stretch and protects his lead through the final rounds. Coverage additionally highlights Koivun’s background as a highly regarded former amateur and his rapid transition to the pro level, culminating in a maiden PGA Tour victory.
