Zach Johnson, one stroke off the lead after round one, did not birdie any of the four par-five holes at the Plantation Course, but picked up four shots in five holes on the front nine and three more birdies on the way home, hitting 16 of the 18 greens in regulation.

The 10-time winner on the PGA Tour, who has had seven top-10 finishes in his past 10 official PGA Tour events, said: "I don't know how many years I've been here, seven or eight probably, and I've had one or two decent finishes, but nothing so spectacular.

"The more I get my feet here walking these grounds, I think the more comfortable I become."

Namesake Dustin used his considerable length off the tee to birdie all four of the par-fives. He collected six birdies on the front nine and recovered from two short missed putts for bogeys at the 11th and 13th to add three more birdies on the back nine.

In addition to his long hitting, the 29-year-old holed from 27 feet at the seventh and said: "This golf course sets up well for me.

"I can reach all the par-fives, and there are a few short holes where you can drive it up close to the green. So if I chip and putt it well, I'm going to shoot a good score pretty much every time."

Masters champion Scott, 33, had five birdies but dropped shots at the 13th and 16th and lies 12th in the 30-man field.
