Snedeker, Singh among leaders in Hawaii
Brandt Snedeker and Vijay Singh are part of a five-way share of the lead after the Sony Open first round on Thursday.
Singh, 52, and Snedeker - who was tied for third at the Tournament of Champions - carded seven-under 63s at Waialae Country Club in Honolulu.
They are joined at seven under by American trio Kevin Kisner, Ricky Barnes and Morgan Hoffmann.
A three-time major winner and 2005 Sony Open champion, Fijian Singh produced a bogey-free round that included back-to-back birdies at holes one and two, and eight and nine.
Singh's last and 34th win on the PGA Tour came in 2008.
Snedeker, who had missed three consecutive cuts leading into last week, had an eagle and bogey as well as six birdies.
Like Singh, Barnes went through bogey-free, while Kisner and Hoffmann had one each in their strong starts.
Americans Zach Johnson and Charles Howell III and South Korean Kim Si-woo are tied for sixth a shot back, while a group of 11 players are at five under.
Among them is Luke Donald, who holed a 38-foot eagle putt on his final hole, David Lingmerth and Scott Piercy.
Two-time defending champion Jimmy Walker struggled with an eagle, birdie and two bogeys to be one under.
Australian Adam Scott, eyeing the number one ranking once more, carded a 68 to be tied for 52nd.
