Notable Notes: Lou Graham defeated John Mahaffey in an 18-hole playoff for the trophy. The pair tied after 72 holes at 3-over 287. In the playoff, Graham took a 3-stroke lead with a birdie on the 12th hole and Mahaffey was never closer than two strokes after that. Their final scores were 71 for Graham and 73 for Mahaffey.
Tom Watson opened the tournament by tying the then-U.S. Open record for 36 holes of 135. But he was 20 strokes worse over the final two holes. ... Jack Nicklaus just missed a birdie putt on the 15th hole in the final round that would have tied him for the lead, then he bogeyed the final three holes. ... This was the final U.S. Open in which players were not allowed to use their own caddies (they had to use caddies provided by the club).
Graham was 11 strokes behind leader Watson after 36 holes. He still holds the tournament record for largest comeback after 36 holes by the winner.
