In 2010, a then 16-year-old Spieth had begun making a name for himself at the junior golf level, having won the U.S. Junior Amateur title the previous summer (one of two he would win) and being named the AJGA Rolex Player of the Year.
However novice exemptions had been uncommon, notably for schoolboys, and he crafted the letter fastidiously with the assistance of his father and others.
"Now I wish to create comparable reminiscences for different children who could someday love the sport like I do", he wrote.
He also told tournament chief George Conant how his friend Justin Thomas - now the world No.1 - had made the cut at the Tour's Wyndham Championship and how another of his junior colleagues, Matteo Manassero, had finished tied 13th at the British Open.
It was not so long ago that three-time major victor Jordan Spieth, 24, was trying to make his way into a PGA Tour event. He became world No.1 for the first time later that year.
Spieth, who lives in a home previously owned by fellow Tour star Hunter Mahan in Dallas, is a daily at Trinity Forest and admits he rides golfboards - like surfboards on wheels - with music blaring as he performs the course with mates.
"It was unreal. I learned so much that week", Spieth says.
"It's good for pace of play and so we typically go out with four, five guys all on golfboards and just cruise around and, you know, in three and a half hours with a five-some and it's a blast".
Spieth will play alongside former US Open champion Graeme McDowell of Northern Eire and fellow Texan Jimmy Walker, who's again in kind with a tied second on the Gamers after a prolonged battle with Lyme illness.
