It was the first PGA Championship held in its current stroke play format,[3] 72 holes over four days, ending on Sunday.

The announcement of the change was made eight months earlier in November.

[6] Sam Snead led after 54 holes in pursuit of a fourth title, but faded to third with a final round 73 (+3).

The Open Championship was held two weeks earlier in England at Royal Lytham & St Annes, with only two Americans in the field; Gene Sarazen finished 16th, but missed the first cut at the PGA Championship.
