Stuart Appleby is not in the field at the Masters this year, but the Australian PGA Tour veteran has played in the tournament 14 times. While his career-best finish was T-7 in 2007, Appleby has played the event enough to know Augusta National's famed course very well.
Like every pro, he keeps a yardage book of the layout, which includes knowledge and notes stored up over the years. On Sunday, Appleby tweeted photos of the notes for each hole at ANGC. It's a rare look into how much time and effort Tour pros put into their preparation. Check out the photos below.
