1970 British Open

July 11, 1970 – St. Andrews (Old Course), St. Andrews, Scotland

Had Doug Sanders hit a 3 1/2-foot, downhill putt at 18 on Sunday to win the British Open, Nicklaus would have been denied his second Claret Jug. But that historic miss opened the door for Nicklaus to tie in regulation and win it in an 18-hole playoff by a single shot with a 72.
