WHITE SULPHUR SPRINGS, W.Va., July 5 (UPI) -- Vijay Singh
, holder of the PGA Tour record for most wins over age 40, took the lead at the Greenbrier Classic Thursday with his lowest round in six years.
Singh, 49, shot a 7-under 63 in the opening round to lead Jeff Maggert, Martin Flores and Jonathan Byrd by one shot.
Tiger Woods, coming off his tour-best third win of the season, settled for a 71 that left him in a tie for 88th place. Phil Mickelson shot the same score.
John Daly (68) and 62-year-old Tom Watson (70) were among those who finished in front of Woods and Mickelson Thursday.
Singh won his 12th PGA Tour event a month before his 40th birthday in 2003 and since then has won 22 more times. His 63 Thursday was his best round on the tour since he fired a 61 at the 2006 Deutsch Bank Championship, where he eventually finished second.
He birdied six of the last eight holes at the Old White-TPC course in a bid to win on the tour for the first time in four years.
Those tied for fifth at 65 included Garth Mulroy, Andres Romero, J.B. Holmes and recent U.S. Open winner Webb Simpson.
There were 62 sub-par scores turned in during the opening round. Defending champion Scott Stallings had a 67.
