Vijay Singh, a 52-year-old Fijian who hasn't won on the PGA Tour in more than seven years, shares the lead after the first round at the Sony Open in Hawaii on Thursday.
In a bogey-free round, Singh opened with back-to-back birdies and added consecutive birdies at Nos. 8 and 9.
Singh owns 59 worldwide victories, 34 of them on the PGA Tour. He captured the PGA Championship in 1998 and 2004 as well as the Masters in 2000.
He won at Waialae in 2005. If he comes out on top Sunday, he would be the oldest-ever PGA Tour champion at 52 years, 10 months and 26 days old -- 18 days older than Sam Snead was when he captured the 1965 Wyndham Championship.
Hoffmann started his round with a bogey at No. 10, his only miscue of the day. He followed with six birdies, then closed his round with an eagle on No. 9.
Barnes played a bogey-free round, while Kisner made eight birdies and one bogey. Snedeker eagled the par-4 10th hole, and he had six birdies and a lone bogey.
The last time the Sony Open had at least five players on top after the opening round was 2010, when six were tied at 65. Among that sextet was Ryan Palmer, who went on to record a one-shot victory over Robert Allenby.
Jimmy Walker, the two-time defending Sony Open champion, opened with a 69. His round included an eagle on the par-5 ninth hole, when he sank a 12-foot putt. He had two bogeys and made his lone birdies on No. 18.
