Jack Nicklaus won the second of his five PGA Championships, two strokes ahead of Billy Casper, the reigning Masters champion.

Nicklaus led wire-to-wire,[4][5] and held a four-stroke lead over Gary Player after 54 holes, with Casper seven shots back.

[6] The two were pre-tournament favorites, along with Arnold Palmer,[7] who shot an opening round 75 and finished at 289 (+1), eight strokes back.

[8] Nicklaus became the first in history to complete the modern career Grand Slam for a second time; two victories in each of the four major championships.

The championship was played in February rather than August, due to anticipated oppressive summer weather in Florida.
