OAKMONT, Pa. (AP) — J.J. Spaun handled the toughest test with a club that never fails any U.S. Open. His putter carried him to a 4-under 66, only the second bogey-free round in the last three U.S. Opens at Oakmont for an early one-shot lead.

Unheralded J.J. Spaun outshined the game's top players and led the U.S. Open by one shot after the first round on Thursday at steamy Oakmont Country Club where the big names like Scottie Scheffler, Bryson DeChambeau and Rory McIlroy all struggled.

Spaun went out in a record 31 and posted just the eighth bogey-free round in U.S. Open history at Oakmont to take the early lead on Thursday.
