Golf's biggest names slipped up and most Australians perished in a typically rough start to the US Open at fearsome Oakmont Country Club in Pennsylvania.
American JJ Spaun produced a majestic bogey-free four-under 66 to claim a one-shot first-round lead as only 10 players in the 156-man field broke par on the Open rota's most difficult layout.
There were shanks and air-swings from the savage rough as 16 players shot 80 or worse, including American qualifier George Duangmanee, who propped up the field with a 16-over-par 86.
