1966 U.S. Amateur: Gary Cowan wins at Merion Golf Club (East Course)

What happened at the 1966 U.S. Amateur

Beman, leading by three with two to play, bogeyed the 17th and double-bogeyed the 18th (3-iron into a bunker, blade over the green, chip short) to fall into a tie with Cowan, who had closed with a 67 including four birdies in the last seven holes

In the Sunday playoff Beman three-putted the 224-yard 17th from 15 feet, missing from three feet, and Cowan saved par from the fringe on 17 and 18 to win 75-76

Final round, Gary Cowan v. Deane Beman, tie at 285. Beman came to the last two holes three strokes ahead; he bogeyed 17 after a bad bunker shot and made a double-bogey 6 at the 18th (approach into a bunker, blast over the green near a TV tower, chip short, chip to 15 inches). Cowan, who shot 67, watched from the locker room.

Playoff, Gary Cowan v. Deane Beman, Cowan 75, Beman 76. Even through 14 holes of an error-strewn 18-hole playoff; Beman three-putted the 17th (missing a three-footer) to fall one behind and Cowan parred in from the fringe.

No draw: stroke play

From 1965 to 1972 the U.S. Amateur was 72 holes of stroke play, so there is no bracket for 1966.
