Charles Coody, 1971
Coody, 33, led after a first-round 66 and was tied for the lead with Nicklaus after 54 holes. In the final round Coody birdied 15 and 16 to beat Nicklaus and Johnny Miller by two strokes.
The Masters was Coody's third and final Tour victory, though he won five times on the Champions tour.
Tommy Aaron, 1973
Trailing by four after 54 holes, Aaron closed with a 68 to win by one over J.C. Snead.
The Masters victory was the second and last Tour triumph of Aaron's career, and he never had another top 10 in a major. He won once on the Champions tour.
