Old Course and Bobby Jones
Bobby Jones (who later founded Augusta National) first played St Andrews in the 1921 Open Championship. During the third round, he infamously hit his ball into a bunker on the 11th hole. After he took four swings at the ball and still could not get out, he walked off the course. Six years later, when the Open Championship returned to St Andrews, Jones also returned. Not only did he win, he also became the first amateur to win back-to-back Open Championships. He won wire-to-wire, shooting a 285 (7-under-par), which was the lowest score at either a U.S. Open or Open Championship at the time. He ended up winning the tournament by a decisive six strokes.
