Jack Nicklaus shares his original letter about turning professional

Nicklaus owns the most major championship victories of all time.

Golf legend Jack Nicklaus shared a blast from the past Tuesday by tweeting out his 1961 letter informing the USGA of his intent to turn professional.

"It is with mixed emotions and considerable thought that I am writing this letter to you of my intentions to apply for membership in the Professional Golf Association," Nicklaus opened a letter dated Nov. 7, 1961, to USGA executive director Joseph Day Jr.

It's been 56 years since Nicklaus made the tough decision to leave Ohio State for the PGA Tour. In the end, it proved a great decision, as Nicklaus went on to win a record 18 major championships.

Nicklaus, 77, still plays a large part on the PGA Tour scene, hosting the Memorial Tournament and serving as mentor to some of the game's bright young stars.

Athletes in all sports these days face tough decisions regarding their amateur status, so it's interesting to see Nicklaus' struggle to make that decision in a completely different era.
