The 1968 PGA Championship was the 50th PGA Championship played July 18–21 at Pecan Valley Golf Club in San Antonio, Texas. Julius Boros, age 48, won the third of his three major titles, one stroke ahead of runners-up Bob Charles and Arnold Palmer. Boros was the oldest winner of a major championship for over a half century, until Phil Mickelson won in the PGA Championship in 2021 at age fifty. The tournament was played in very hot conditions. Palmer had an 8-foot (2.4 m) putt to tie on the 72nd green, but it missed on the high side of the hole. It was the second of his three runner-up finishes at the only major he never won; he also tied for second in 1964 and 1970.
