One guy that we're leaving out of this discussion is Ben Hogan and his triple crown in 1953.
- Going into 1953, only once before had all 4 majors in a year been won by Americans
- this was after the car accident that almost took away his ability to walk
- He sets the Masters scoring record that stood until Jack Nicklaus beat it
- Wins the US Open at Oakmont when all but 1 player had to qualify for it (including Hogan). The event included a 36 hole final day that he had to walk with his damaged body.
- Then wins the British at Carnoustie in his only appearance ever in the event with little to no experience playing links golf and his first time playing the smaller 1.62" ball.
- Hogan couldn't play in the PGA because of the scheduling conflict between it and the British. He also wasn't playing the PGA annually at that point because it required 5 straight days of 36 holes to win it.
The next major that Hogan did play in was the 1954 Masters, in which he was tied for the lead after 72 holes and then lost by one shot in an 18 hole playoff to Sam Snead.
So, Hogan was 1 stroke away from essentially completing the Tiger slam if you excuse him from the fact that it was impossible for any player in 1953 to play in all 4 majors due to the overlap in dates.
Look at the run that Hogan went on from 1948 through 1956- these were his finishes in every major that he played in during that stretch: T6, 1, 1, T4, 1, 1, 1, T7, 3, 1, 1, 1, 2, T6, 2, 2, T8, T2 (at one point in that streak, he won 8 out of 11 that he played in).
That to me is the greatest stretch of golf in majors ever.
