Claim: Dick Hart, an American professional golfer who played on the PGA Tour in the 1960s, was the champion of the 1963 PGA Championship with a score of 66.
Evidence: At the 1963 PGA Championship, Hart led after both 18 and 36 holes (66 & 72) but faded in the third and fourth rounds (76 & 74) to finish the tournament at T-17 — his best finish in a major championship. 
Jack Nicklaus won the first of his five PGA Championship titles, two strokes ahead of runner-up Dave Ragan.
