J.J. Spaun impressed everyone at the 2025 U.S. Open with a flawless round, shooting a remarkable 4-under 66 to secure the top spot on the leaderboard. This marks Spaun's best career round in a major tournament, achieved at the challenging Oakmont venue.

Starting on the back nine, Spaun began his day on a high note by chipping in for a birdie on the 10th hole. He continued his stellar play, adding three more birdies on his first nine, highlighted by an impressive tee shot on the par-3 16th.

As conditions toughened on the front nine, Spaun faced some challenges off the tee but showcased his skills on the greens with remarkable escapes to save pars. Despite a shaky ball-striking performance on the second nine, Spaun managed to maintain his composure and finish with a bogey-free round.

This exceptional performance by Spaun is the first bogey-free round at Oakmont in the U.S. Open since Dustin Johnson's victory in 2016. With his solid putting and resilient play, Spaun is positioned as the solo leader for the day, setting a high bar for the rest of the field to match.

Although Spaun will need to fine-tune his ball-striking, his strong putting gives him a competitive edge for the upcoming rounds. If he can maintain his putting form, Spaun has a promising chance to remain a top contender throughout the tournament.
