American Wyndham Clark has won the U.S. Open by one shot over Rory McIlroy at the Los Angeles Country Club to claim his first major title.
Clark sank a short par putt on 18 to finish the championship on 10-under par behind an impressive display of power and precision.
"I've worked so hard and dreamed about this moment for so long," said Clark while collecting the trophy and winner's check of $US3.6 million.
"So many times I've visualized being in front of you guys and winning this championship. I felt like it was my time."
World number one Scottie Scheffler was third at seven under while overnight co-leader Rickie Fowler faded early and had to settle for a share of fifth.
Clark said he drew inspiration from his late mother.
"I felt like my mom was watching over me today," said Clark, who considered quitting golf a decade ago after his mother died of breast cancer.
New Zealand's Ryan Fox finished tied for 43rd, finishing at five over par for the tournament.
