Adam Scott has fired a second consecutive three-under-par 70 only to find himself seven shots adrift of Tournament of Champions leader Zach Johnson.

World No.2 Scott compiled five birdies but bogeyed the 13th and 16th in Kapalua, Hawaii on Saturday to be in 12th place in the 30-man field of winners on the US PGA Tour last year.

One of the hottest players in world golf, Johnson stole a three-shot lead with his bogey-free 66 to reach 13-under at the halfway point.

Noted for his accuracy and short game, 2007 Masters champion Johnson has recorded seven top-10 finishes in his past 10 official US tour events dating back to July’s John Deere Classic.

“The more I get my feet here, the more I walk these grounds, the more comfortable I become,” Johnson told PGATour.com after hitting 16 of 18 greens in regulation and taking 30 putts at Kapalua.

Defending champion Dustin Johnson (66) was tied for second with Jordan Spieth (70) and Matt Kuchar (68) at 10-under.
