U.S. Open winner J.J. Spaun jumped to No. 8 in the Official World Golf Rankings released Monday, a meteoric rise from 109th to begin the season. Spaun began last week ranked 28th in the OWGR before he scored a two-stroke victory over Robert MacIntyre of Scotland with consecutive birdies in his final round at Oakmont Country Club on Sunday to win the U.

J.J. Spaun, who won the U.S. Open on Sunday at Oakmont Country Club, moved to eighth in the world rankings, the highest spot of his career. When 2025 began, he was outside the top 100. But even he hasn't made the biggest jump this year.
