Two-time US Open champion Lee Janzen was unceremoniously booted out of this year's event after being disqualified for wearing the wrong type of golf shoe during pre-qualifying.
The winner in 1993, and again five years later, was shown the door after it emerged he was wearing steel spikes at Woodmont Country Club in Maryland.
This violated a club rule which meant he was unable to play the second round of the 36-hole qualifying event at the Rockville course.
Janzen had fired a 75 in his opening round and would have had to shoot a 61 on his second circuit anyway to force his way into a sudden-death play-off.
One of the joint leading qualifiers at Woodmont was Scot Russell Knox with rounds of 65 and 67.
Elsewhere, Irish amateur Kevin Phelan topped qualifying at Bradenton in Florida with rounds of 65 and 70.
At Brookside in Columbus, where many tour pros were attempting to qualify, Robert Karlsson safely made it to next week's second major championship of the season.
The Swede posted rounds of 66 and 68 to tie for second behind winner Charley Hoffman.
But the casualties in Ohio included Americans Davis Love and Ben Curtis, Aussies Robert Allenby and Stuart Appleby, along with South African Trevor Immelman and Camillo Villegas of Colombia.
In all, eleven sites conducted 36-hole sectional qualifying events for the US Open at Merion near Philadelphia which starts on June 13.
