HONOLULU (REUTERS) - Former world No. 1 and 2005 champion Vijay Singh rolled back the years as he charged into a share of the early lead with a sizzling seven-under 63 in the opening round of the Sony Open in Honolulu, Hawaii on Thursday.

Seeking his first PGA Tour victory since the 2008 Deutsche Bank Championship, the tall Fijian racked up seven birdies on the tight, palm tree-lined layout at Waialae Country Club to finish level with Americans Ricky Barnes and Morgan Hoffmann.

Vijay, 52, narrowly missed a nine-foot putt for eagle on his final hole, the par-five ninth, as he ended a bogey-free display with consecutive birdies for a three-way tie at the top after taking advantage of relatively benign morning conditions.

South Korea's Kim Si Woo carded a 64 in the PGA Tour's first full-field event of the year while another former world No. 1, England's Luke Donald, was among six players who opened with 65s.

Level with Donald were Americans Sean O'Hair, Shane Bertsch, Zac Blair and 2002 Sony Open champion Jerry Kelly, and Canadian David Hearn.
