Michael Letzig and Kent Jones carded bogey-free opening-round seven-under-par 65s to open up a two-stroke lead at the Ginn Sur Mer Classic on Friday.
Ryan Palmer (67) sits two strokes adrift, with Australian Robert Allenby and American trio Cameron Beckman, James Driscoll and Tom Scherrer a further shot back.
After his first birdie on the par-three third, Letzig reeled off three straight from the sixth before the American, who has four top-10 finishes in 28 events this season, added three more on the back nine.
Jones reached the turn in two under before propelling himself up the leaderboard with five birdies on the way home.
Starting on the back nine, Palmer opened with three birdies in his first six holes, while Beckman, who won last week's Frys.com Open, birdied three of his last five holes to sign for his 68.
Defending champion Daniel Chopra endured a horrific start with an 81, which included six bogeys and a pair of double bogeys, and sits in last place.
The round was suspended due to darkness with five players still on the course.
