American Nick Watney benefited from a late stumble by compatriot Brandt Snedeker to snatch a one-shot lead in the Mercedes-Benz Championship first round.

Making his debut in the winners-only event, Watney upstaged some of the biggest names in the game by firing a five-under-par 68 on the hilly Plantation Course at the Kapalua Resort.
   
The 26-year-old Californian piled up six birdies, his last with a 30-foot putt on the 17th to take the outright lead, against a lone bogey in blustery, wet conditions to take charge of the PGA Tour's opening event of 2008.
   
"I putted very well and I kept it really simple," Watney told reporters after ending the day a stroke in front of Swede Daniel Chopra. "I just hit to a lot of the middle of the greens and tried to take what they gave me.
   
"It was a very steady day and I'm very pleased but, at the same time, it's the first day of the first tournament of the year, so we've got a long ways to go."
   
Australian Aaron Baddeley birdied four of the last five holes for a 70, matching US Open champion Angel Cabrera and American Jonathan Byrd in the tournament which brings together the title holders from the previous PGA Tour season.
   
Snedeker, battling to shrug off a lingering bout of flu, dropped three shots in the last two holes for a 71 to finish level with 2003 Masters champion Mike Weir.
   
Canadian Stephen Ames, who struck the opening drive of the season, American left-hander Steve Flesch and South African Rory Sabbatini were a further stroke back after carding 72s.
   
Snedeker, the 2007 PGA Tour rookie of the year, had led by a stroke before running up a double-bogey six at the 17th after missing the fairway to the left off the tee with a cracked driver.
   
Forced to use his three-wood twice on the 663-yard par-five last, he signed off with a bogey after three-putting.
   
Among the big names, world number three Jim Furyk and defending champion Vijay Singh opened with 74s.
   
Masters champion Zach Johnson battled to a 76 while fellow American Paul Goydos propped up the leaderboard with a poor 81.
