Johnson’s holed approach at the par 4 10th kick started a final nine of 29 to move one clear of Ryan Blaum and Andrew Putnam with C.T. Pan and Wesley Bryan another shot back.
Johnson, the current world number two, has not won since his win in the opening event of the year in Hawaii but he has continued to play well and appears to be peaking for another US Open tilt next week at Shinnecock Hills.
Johnson won the US Open at the Oakmont Country Club in 2016 to record his only major title amongst 18 PGA Tour titles.
His efforts this week have been made even more impressive given he took a double bogey at the 9th hole of yesterday's opening round. In all he has produced twelve birdies and an eagle thus far.
Stuart Appleby is the best of the Australians at 4 under and in a share of 15th place while Matt Jones is another shots back, Cameron Percy two shots further behind Jones while Aaron Baddeley made the cut on the number.
