Actually, most of the biggest weather disasters have been at non-majors. The 1996 AT&T Pebble Beach National Pro-Am was canceled after 36 holes because rains caused the 16th at Spyglass Hill, one of the three courses in the tournament rotation, to have so much casual water that it became unplayable under the Rules of Golf. Since some of the players in the field had played Spyglass, but those who hadn’t could no longer play the same 18 holes, it was decided—controversially—that the competition could not be equitably completed.
