Trevino, 40, had won the last Open played at Muirfield in 1972, successfully defending his 1971 title and ending the grand slam bid of Jack Nicklaus. Nicklaus, also 40, tied for fourth. He won at Muirfield in 1966 and was runner-up by a stroke in 1972.

This was the first Open scheduled to end on a Sunday, with a Thursday start. The Open previously began on Wednesday and ended on Saturday. Prior to 1966, the final two rounds were scheduled for Friday.
