The 1948 PGA Championship was the 30th PGA Championship, held May 19–25 at Norwood Hills Country Club in St. Louis, Missouri. Ben Hogan won the match play championship, 7 & 6 over Mike Turnesa in the Tuesday final; the winner's share was $3,500 and the runner-up's was $1,500.
It was Hogan's second and final PGA Championship victory and the second of his eight major titles; the third came a few weeks later at the U.S. Open. Following a near-fatal auto accident in early 1949, his debilitated condition did not agree with the grueling five-day schedule of 36 holes per day in summer heat. Hogan did not enter the PGA Championship again until 1960, its third year as a 72-hole stroke play event, at 18 holes per day.
Defending champion Jim Ferrier lost in the second round to semifinalist Claude Harmon, 1 up. Harmon defeated Sam Snead in 42 holes in the quarterfinals, but was stopped by Turnesa in 37 holes in the next round.
Hogan became only the second of four players in history to win the U.S. Open and the PGA Championship in the same calendar year. He was preceded by Gene Sarazen in 1922 and followed by Jack Nicklaus in 1980. Through 2015, Tiger Woods is the last to win both, in 2000, part of his Tiger Slam of four consecutive majors.
