How to unlock the Mystic Rock Open achievement in John Daly's ProStroke Golf - Definitive Guide
Once you've beaten all 4 Mystic Rock challenges in "Career Mode" the course will then become available for tournament play (also found under "Career Mode"). This is only a 9-hole event, and like the description says, you just have to finish within 8 shots of the leader for the trophy to unlock.
