His thrilling victory at Oakmont Country Club on Sunday was another example of the inspiring resilience of a San Dimas High graduate who never forgot his roots.

J.J. Spaun's Sunday at Oakmont to win the 2025 U.S. Open was one of the craziest final rounds from a major champion in recent memory. He began his day with five bogeys in his first six holes, going from tied at 2nd to five shots back of the lead before even making the turn.

In one of the most improbable wins in U.S. Open history, J.J. Spaun started the final round with five bogeys in the first six holes, stood four shots back with nine holes to play then came home in 32 to win at rain-laden Oakmont C.C.

J. Spaun won the 125th U.S. Open at Oakmont Country Club after sinking an impressive putt from 64 feet away from the hole. He joins TODAY, along with his caddie Mark Carens, to talk about getting his “head back in the game” for the back nine after a rougher first half to his game and how he was up late the night before while his youngest daughter was fighting a bug.

I tried to just continue to dig deep,” he J.J. Spaun said after winning the 2025 U.S. Open at Oakmont. “I've been doing it my whole life.”

The 36-year-old San Dimas High graduate is the only player to finish under par, capping a wild final round with two closing birdies to claim his first major title.
