1. A first-round 91 from the champion (Newport, 1895)
Horace Rawlins rallies with a second-round 82 to win inaugural. Last 50 years the winner's highest opening-day score has been 75 (Larry Nelson, 1983; Raymond Floyd, 1986).
2. A 72-hole playoff (Inverness, 1931)
Billy Burke and George Von Elm need second 36-hole playoff when they remain tied after the first.
3. A 19 on one hole (Cherry Hills, 1938)
Hitting his approach into the creek guarding the par-5 16th, Ray Ainsley stubbornly tries playing the ball, refusing to take a drop. Eventually getting it out and onto the green, he one-putts for a 19. Elapsed time: 30 minutes.
4. Nineteen starts by an amateur
Charles (Chick) Evans Jr.'s first was in 1914 and last was in 1954. Worst finish in first 10 starts: 18th place.
5. An impostor playing the course (Baltusrol, 1980)
In a practice round, 7-handicap Barry Bremen poses as qualifier Chuck Moran. Joining Bobby Nichols and Jim Thorpe on the fourth hole, he makes it to 18 before being caught.
6. A contestant wearing shorts (Oakmont, 1983)
Admonished for them in practice rounds, Forrest Fezler changes into navy-blue shorts for the final hole.
7. 18 top-10 finishes
Jack Nicklaus' feat seems safe as no current player has more than seven (Ernie Els, Phil Mickelson, Jeff Maggert and Vijay Singh). Tiger Woods has five.
8. 124 rounds under par (Medinah, 1990)
Since that birdie binge the biggest total has been 83 at Olympia Fields in 2003. Last year at Oakmont, it was seven.
9. Two nine-hole 29s by one player (Shinnecock Hills, 1995; Oakland Hills, 1996)
Neal Lancaster has accomplished the once-in-a-lifetime feat twice. Only other to do it once is Vijay Singh (2003).
10. A 15-shot victory (Pebble Beach, 2000)
Prior to Woods' rout, largest margin was 11 set in 1899.
