AVONDALE, La. -- Ricky Barnes said he still owes his newborn daughter a late birthday present.
Perhaps a piece of silver would be appropriate.
Barnes birdied six of the last eight holes Thursday at rain-softened TPC Louisiana to take a one-stroke lead at the Zurich Classic of New Orleans, which awards a silver cup to the winner.
Barnes finished the opening round with an eagle, seven birdies and a bogey for an 8-under 64. Boo Weekley and Lucas Glover were a stroke back, and D.A. Points and Morgan Hoffmann shot 66.
"Today it was nice because it was a pretty stress-free round," said Barnes, who did not arrive in New Orleans until late Wednesday afternoon after the birth of his daughter Monday night. "I think I only had to chip once in 18 holes so that's nice."
Guan Tianlang, the 14-year-old Chinese amateur playing on a sponsor exemption, opened with an even-par 72, highlighted by a 5-wood that he hit to a foot on the par-3 17th.
"I think I played pretty good golf," Guan said. "Not the best but I made some ups and downs and a couple birdies."
He tied for 58th in the Masters after becoming the youngest player to make the cut at Augusta National, and said Thursday that he will play in a U.S. Open qualifier in two weeks in Dallas.
Calgary's Stephen Ames, Ernie Els and Rickie Fowler are in a group of 10 players at 5 under. Graham DeLaet of Weyburn, Sask., is another shot back at 4-under 68. Defending champion Jason Duffner and Ottawa's Brad Fritsch opened with a 70.
David Hearn of Brantford, Ont., had a 71 and Mike Weir of Brights Grove, Ont., shot a 72.
Bubba Watson, the 2011 champion, carded a 73.
Eighty-four players were at 1 under or better on the rain-softened TPC tract, with 30 players within 4 shots of the lead. Heavy rains that spawned at least two tornadoes in the New Orleans area Wednesday left TPC's normally firm greens soft and defenceless.
Players were allowed to lift clean and place their golf balls in the fairways, which especially benefited the later players after an early mist gave way to sunny and ideal scoring conditions.
Barnes missed the cuts in seven of his last eight events. He jump-started his round with the eagle on the par-5 second hole, hitting a 3-wood from 294 yards to 12 feet.
"That kind of got the round going," he said. "I was 3 under (after a birdie at the fourth) and those are the kind of starts I need."
Barnes birdied the par-5 11th, had four consecutive birdies on Nos. 13-16 and finished with a birdie on the par-5 18th. He hit all 14 fairways in regulation and had 26 putts.
Barnes said a new, albeit unusual, pre-putt routine has helped his focus. He uses a left-hand low grip for the practice stroke and a "claw" grip for the actual stroke.
"If you watch a lot of guys that (putt) cross-hand, their shoulders are able to stay very level," he said. "It's a good way of getting the feeling of hitting down on the ball."
The stage might be set for another Barnes-Glover shootout, similar to the 2009 U.S. Open at Bethpage in New York when the duo battled in the final three rounds. Glover eventually overtook Barnes in the final round to win his only major championship.
Glover birdied his first four holes, playing the back nine first, to get to 6 under. After a bogey on the sixth, he closed the round with birdies on the eighth and ninth holes.
"Any time you can climb up the board in the afternoon, it feels pretty good," said Glover, who had a 12:30 p.m. tee time. "I hit it like I've been hitting it and finally putted well."
Weekley, fighting a sinus infection, made a 27-foot putt on the final hole to climb into a tie for second.
"It was good. It could have gotten real good if some of them putts would have fallen early in the round," Weekley said. "I left at least four on the front side that were good birdie putts. I had good looks at them."
DIVOTS: Spectators and at least one marshal were startled when an alligator, estimated to be about 12 feet, spent some of the afternoon sunning itself on the left side of the 12th fairway before making his way back to the water through bunker. Observers said it was "Tripod," a three-legged gator that has become somewhat of a regular at the course. ... Eight marshal captains wore Boston Red Sox hats in honour of the victims of the Boston Marathon bombing. ... Barnes' only other lead after any round was the second and third rounds of the 2009 U.S. Open.
