Vijay Singh, 52 and bidding to become the oldest winner in PGA Tour history, shot a seven-under par 63 in the first round of the Sony Open in Hawaii, and shares the lead with Brandt Snedeker, Kevin Kisner, Ricky Barnes and Morgan Hoffman.
Singh turns 53 in one month. Sam Snead was 52 years, 10 months, when he won the Greater Greensboro Open in 1965.
Singh was bogey free and birdied the final two holes at Waialae Country Club. Seven-under was Singh's lowest opening round score in more than three years. He won the Sony Open in 2005 when he was ranked No. 1 in the world, and has not won a tour event since the Deutsche Bank Championship in 2008.
"I've been playing really well," Singh said. "I just haven't produced the scores. I feel I'm playing well, and see what the next three days bring."
Jimmy Walker, aiming for his third straight victory in this tournament, shot a one-under 69, placing him tied for 66th after the first round.
Robert Allenby, returning to the Sony Open after his ordeal there a year ago, shot an opening round three-over 73, tied for 130th.
Other players off to strong starts include Si Woo Kim and Zach Johnson (six-under, tied for sixth) and Tony Finau and Luke Donald (five-under, tied for eighth).
