Jonathan Kaye held the lead with four other players as the weather wreaked havoc on the opening day of the AT&T Classic at TPC Sugarloaf .
Kaye shot a six-under-par 66 to share the clubhouse lead with Ryan Palmer, Jonathan Byrd, Parker McLachlin and Kenny Perry as torrential rain stopped play for half an hour in the afternoon and caused a large back-up that prevented 34 players from finishing their rounds.
The 37-year-old, who was once as high as 14th in the world ranking, has had his career derailed by injuries and is playing for the first time since tying for 75th at the Zurich Classic in late March.
He took full advantage of the more favourable conditions in the morning, making birdies at his final two holes in a bogey-free round.
Byrd recovered from a double bogey on the seventh with five birdies on his back nine to join the crowd at the top of the leaderboard.
Charles Howell III, David Toms, Ted Purdy and Bob Sowards are one shot off the pace on five-under 67 with another 10 players just a further shot back.
Defending champion Zach Johnson battled through the inclement conditions in the afternoon to card a three-under 69 with five birdies and a bogey.
Johnson defeated Ryuji Imada in a play-off last season for his second win of the season in Georgia following his victory at the Masters earlier in the season.
