J.J. Spaun Leads 2025 U.S. Open After Day One at Oakmont

After the first round of the 125th U.S. Open at Oakmont Country Club, J.J. Spaun leads with a 4-under 66, holding a one-stroke advantage over the field. The course proved challenging, with a field average score of 74.63, marking the highest opening round at a U.S. Open since 2018. Notable players such as Jon Rahm, the current favorite to win at +550 odds, opened with a solid 69, while Scottie Scheffler and Bryson DeChambeau struggled with 3-over 73s and sit near the projected cut line. Several former champions including Rory McIlroy, Matt Fitzpatrick, Wyndham Clark, Dustin Johnson, and others face the risk of missing the cut if they do not improve, with cut line projections around three over par. Brooks Koepka posted an impressive 2-under 68, signaling a possible resurgence, while Shane Lowry and others remain further back with higher scores. The U.S. Open's notoriously difficult layout at Oakmont is shaping up for a tough second round where players must elevate their game to advance.
