J.J. Spaun added supreme clarity to one of the most uncertain U.S. Opens by making a 64-foot birdie putt on the 72nd hole to win the 125th edition. It was his first PGA Tour title, a major championship.

The U.S. Open being completed on Sunday is now dependent on the weather and daylight cooperating at Oakmont. NBC's Mike Tirico reported that the U.S. Open could withstand a two-hour weather delay and still finish the final round on Sunday. The delay ended up lasting less than two hours indicating the final round could be completed as scheduled.

The final round of the 2025 U.S. Open Golf Championship takes place on Sunday with three golfers at the top of the leaderboard within one stroke of each other, setting up for a thrilling championship Sunday.

Serving as U.S. Open host for the 10th time, Oakmont has shown its teeth to the field as only four players entered Round 4 with under-par scores. That number is down to one with the first nine having been completed Sunday.
