JJ Spaun surprised the field with a bogey-free 66 at Oakmont Country Club, taking the lead on day one of the US Open. World number one Scottie Scheffler struggled, while Brooks Koepka showed a resurgence of form.
Spaun's Stunning 66 at Oakmont

JJ Spaun's bogey-free 66 was eight shots better than the field average, marking the only bogey-free round. This performance, at only his second US Open, is particularly impressive given the challenging course.
Spaun's confidence stems from a recent Monday playoff against Rory McIlroy at the Players Championship. He stated that the experience, though ending in defeat, built confidence he wouldn't have gained elsewhere.
Scheffler's Disappointing Start

World number one Scottie Scheffler's opening round of 73 was a surprise. While he had three birdies, six bogeys hampered his score. His driving accuracy was below average, and he missed several scoring opportunities.
Despite the poor round, Scheffler remains within striking distance of the lead. His characteristic resilience suggests a strong comeback in the following rounds.
Koepka's Resurgence

Brooks Koepka's 68 showcased a return to form, exceeding expectations after a less-than-stellar recent performance. His round reflected the hallmark major championship play that defined his earlier career.
Koepka attributes his strong performance to a rigorous practice session where his swing coach provided direct and critical feedback, reminiscent of his preparation for previous US Open victories.
Rahm and McIlroy in the Mix

Jon Rahm finished at one under par, placing him in contention. Rory McIlroy's round was marked by inconsistencies, suggesting that he will need to improve for the remaining rounds.
Oakmont's Challenging Course

Oakmont's reputation for difficulty proved true on day one. The scoring average hovered around five over par, highlighting the course's punishing nature. The winning score is predicted to be above par, barring significant rainfall.

CBS Sports Golf analyst Patrick McDonald commented on the day's events and predicted Scottie Scheffler's resurgence in the coming rounds. He expects Scheffler to improve his iron play and putting, bringing his score closer to par.
The Road Ahead

The US Open at Oakmont promises to be a thrilling competition. With Spaun in the lead, but Scheffler and Koepka close behind, the final three rounds are sure to be captivating.
