OAKMONT, Pa. -- The first round of the 125th U.S. Open at Oakmont Country Club is in the books, and though one of golf's toughest tests put several players on their heels Thursday, a handful fought off the course well and headed into Friday with hopes of continuing their strong start.
J.J. Spaun shot a record 31 on his first nine holes of the championship and then held on for his next nine to card a formidable, bogey-free 66 to take the first-round lead. Only nine players behind Spaun are under par.
With 54 holes left, here's what caught our eye Thursday and what we're watching for in the second round.
