Cameron Champ hits his tee shot at the 12th hole during the first round of the 2025 RBC Canadian Open.

The U.S. Open is just about filled up with six available spots still to go. High finishers of the 2025 RBC Canadian Open, if he's not already in the field for Oakmont, earns some tee times at the national championship next week.

The Canadian Open is the final PGA Tour event before the U.S. Open, the final tune-up for those in, the final hope for those not.

There are 29 golfers inside the top 20 (more specifically, there are 29 golfers tied for 18th or better after 36 holes in Toronto). Of those 29, there are 18 who are not in the U.S. Open field.

Kevin Yu, with one PGA Tour in the last year, could have earned a spot with a second PGA Tour. Finishing in the top 60 of the Official World Golf Ranking is a big part of it. Ryan Fox, even with a top-three finish, could earn his way.
