Japan's teenage golf sensation Ryo Ishikawa has set a record that'll be hard to beat on his home tour.
18-year-old Ishikawa teed off in the final round of the Crowns tournament in Nagoya six shots behind the leader, and won by five shots after a magical round of 58, 12 under par.
Ishikawa, the youngest player to win on the Japan tour, and the top money winner last year as a 17-year-old, has now won seven titles.
