Golf’s world number one, American Dustin Johnson has moved to the top of the leader-board after the second round of the AT-and-T Pebble Beach Pro-Am in the USA.

Johnson shares the lead on twelve under par with compatriot Beau Hossler. He followed his opening round of 67 with a second round of seven under par 64 on the Monterey Peninsula course.

The world number one made three birdies in his first four holes.

On the back nine he sunk five more birdies but a solitary bogey prevented him from taking the lead on his own.

It was still his best ever score at the Monterey course beating his previous best by five shots.
