(CNN) -- Nathan Green of Australia and Tom Pernice Jr share the lead after the second round of the Sony Open in Hawaii.
Australian Green shot a second successive four-under-par 66 to share the lead in the Sony Open.
Taking advantage of an early start and pristine conditions at the Waialae Country Club, Green fired his second straight four-under-par 66 and is on 132 after 36 holes.
Green, whose best finish in 90 previous PGA events was second at the Buick Invitational in 2006, had five birdies and one bogey during his second round.
"I don't think the conditions were as bad as we thought they were going to be," he said. "Last night, you could hear the wind whipping. Sort of a stronger version of yesterday. It didn't seem anywhere near as strong as they predicted."
Pernice played later in the day and blistered the course for a 63, firing five birdies and an eagle on the par-five 18.
"Obviously, conditions like this on a challenging golf course make it a very good round," said Pernice. "You're not going out thinking you're going to shoot seven-under. You just kind of plod your way around and try to hang in there.
The pair hold a one-stroke edge over first-round leader Shigeki Maruyama, who fired a 68 to go with his opening 65, and Brian Gay.
Maruyama is on seven-under 133 overall, while Gay fired a 67 to go with his first-round 66. "The greens were a little slower today than they were yesterday," Maruyama said. "But I hit the ball well. I hit some good drives, hit some good second shots and hit some good putts."
Zach Johnson is another shot back, tied for fifth after a hot-and-cold round of 65. The 2007 Masters champion had two bogeys, five birdies and an eagle on the ninth for a five-under-par total. Johnson is level with Webb Simpson on six-under-par.
Geoff Ogilvy, who cruised to a six-stroke victory at the Mercedes-Benz Championship last week, is part of a group on five-under overall. Ogilvy fired a 69 and is tied with Steve Marino, Boo Weekley and Charles Howell III on 135.
