American Wyndham Clark shot a course record 60 to take the lead heading into the final round of the AT&T Pebble Beach Pro Am.
The US Open champion made five putts of at least 25 feet in his 12-under-par round with two eagles, nine birdies and one bogey, eclipsing the previous record of 62.
Clark, who had a lengthy eagle putt at the last to break 60, said he had a “really good feel on the greens”.
