In 1977, Nicklaus won his 63rd tour event, passing Ben Hogan to take second place on the career wins list, behind only Sam Snead (subsequently Hogan's official career PGA Tour victory total was put at 64, including his  1953 Open Championship which was retroactively deemed an official PGA Tour event). He also became the first player to amass over $3million in official PGA Tour earnings. The year also saw Nicklaus win for the first time his own Memorial Tournament, where he described the victory as the most emotional moment of his entire career, and nearly decided to retire from competitive golf.
