The 1937 Masters Tournament was the fourth Masters Tournament, held April 1–4 at Augusta National Golf Club in Augusta, Georgia. Opening with a six-under 66, Byron Nelson led after the first and second rounds, but a 75 on Saturday dropped him four strokes back, in a tie for third. On the final nine on Sunday, he gained six strokes on third round leader Ralph Guldahl over two holes and won the tournament by two strokes. Compared to Guldahl's 5–6 (double bogey, bogey), Nelson played the 12th and 13th holes 2–3 (birdie, eagle), respectively. The Nelson Bridge, over Rae's Creek departing the 13th tee, was dedicated in 1958 to commemorate the feat.
