The 1963 PGA Championship was the 45th PGA Championship, played July 18–21 at the Blue Course of Dallas Athletic Club in Dallas, Texas. Jack Nicklaus won the first of his five PGA Championship titles, two strokes ahead of runner-up Dave Ragan. It was the second major win of the year for Nicklaus, and the third of his eighteen major titles.
Nicklaus entered the final round in third place, three shots behind 54-hole leader Bruce Crampton. Nicklaus shot a three-under 68 while Crampton fell back with 74 (+3) in the Texas heat, with temperatures over 100 °F (38 °C). At the trophy presentation, Nicklaus grasped the very hot Wanamaker Trophy with the aid of a towel.
With the victory, Nicklaus at age 23 joined Gene Sarazen, Byron Nelson, and Ben Hogan as the only winners of all three American majors: the Masters, U.S. Open and PGA Championship. Nicklaus completed the first of his three career grand slams three years later at Muirfield in 1966.
The Open Championship was played the previous week in northeast England at Lytham St Annes, one of five times in the 1960s that these two majors were played in consecutive weeks in July. The PGA Championship moved permanently to August in 1969 (except 1971, when it was played in late February). After cool temperatures in Britain, the oppressive July heat in Dallas was difficult for many to adjust to.
Nicklaus won the Masters in April, marking only the third time that the Masters champion won the PGA Championship in the same calendar year. He was preceded by Sam Snead in 1949 and Jack Burke, Jr. in 1956. Through 2015, it has been accomplished only four times, twice by Nicklaus, and most recently in 1975.
