Palmer lost a stroke at the 10th, then another at the 13th. The players halved the 14th, so to speak, which left Palmer with a 5-stroke lead with four holes to play.

And Casper completely erased that lead over the next three holes. Palmer gave two back at the 15th, then gave up another two on the 16th. When Palmer bogeyed the 17th, the entire 7-stroke lead was gone. Palmer and Casper were tied.

They matched scores on the 18th to finish at 278, seven strokes ahead of Jack Nicklaus in third. Casper and Palmer continued on to an 18-hole playoff the following day, and once again Palmer gave up the lead.

In the playoff, Palmer led by two strokes at the midway point, but lost six strokes to Casper over the final eight holes. Casper won the playoff 69 to 73.

For Casper it was his second win in a U.S. Open, his 30th victory on the PGA Tour. Palmer was runner-up again at the 1967 U.S. Open, completing a six-year period in which he finished second four times in the U.S. Open.

Two-time U.S. Open champion and 40-time PGA Tour winner Cary Middlecoff made his last appearance in this championship this year, withdrawing after the first round. Lee Trevino made his first appearance in a major here, finishing tied for 54th.

And Hale Irwin, later a 3-time U.S. Open winner, made his major championship debut in the 1966 U.S. Open, making the cut as an amateur.

The most impressive amateur, however, was 19-year-old Johnny Miller. Miller grew up playing the Olympic Club, and his course knowledge - not to mention a game that showed flashes of future brilliance - helped him finished tied for eighth in his major championship debut.
