5. 1966 Billy Casper vs. Arnold Palmer
278-278 (Casper won playoff, 69-73)
With nine holes to go, Arnold Palmer was thinking about records, not the 7-shot lead he had over Billy Casper. "In retrospect," says Palmer, "it was the biggest mental error of my career." Had Palmer come home in 1-over-par 36, he would have broken Ben Hogan's U.S. Open scoring record of 276.
However, bogies at 10, 13, 15, 16 and 17 shaved Palmer's lead to one and erased any chance he had of beating Hogan's mark. The train wreck subsided with matching pars at the 18th, but the steady, hot-putting Casper dethroned the King in a playoff the next day.
