Australia's Harrison Endycott has shot a 10 under par 62 on the PGA Tour but isn't close to being the big story of the day as 20-year-old amateur Nick Dunlap sets the golf world buzzing.
Dunlap will bid to become the first amateur to win on the tour since Phil Mickelson 33 years ago when he takes a three-shot lead into the final round of The American Express tournament in California on Sunday (Monday AEDT).
The reigning US Amateur champion, American Dunlap proved steely as he posted a stunning 12-under 60 on Saturday, playing each nine of the La Quinta course - one of three courses in the tournament rotation - in just 30 strokes as he amassed 10 birdies and an eagle to get to 27 under.
