DeChambeau followed what his fellow SMU alum, the late Payne Stewart, accomplished 25 years earlier by winning the U.S. Open at Pinehurst. He is looking for his third U.S. Open title. After going even on the front nine, DeChambeau went 3-over on the back.

Patrick Reed made only the fourth double-eagle since the U.S. Open started keeping records some four decades ago, dunking in his second shot from 286 yards on the par-5 fourth hole at Oakmont.
