NEW ORLEANS -- Vijay Singh made a 25-foot birdie on the 18th hole Monday to win the rain-delayed HP Classic, denying Masters champion Phil Mickelson his second straight victory and Joe Ogilvie his first title.
Singh overcame a six-shot deficit in the last eight holes, using an eagle on No. 15 to shoot 29 on the back nine for a round of 63.
Ogilvie almost forced a playoff after Singh's putt, but his blast out of the sand trap missed by an inch.
Singh finished at 266 and became the first three-time winner on the tour this season, taking $918,000 of the $5.1 million purse. He also won last Monday at the rain-interrupted Houston Open.
Mickelson, playing in his first tournament since winning the Masters, and Ogilvie were a stroke back at 267.
Hidemichi Tanaka was fourth at 269 while Charles Howell and Justin Rose tied for fifth at 271. Three players, including former champion K.J. Choi, were tied at seventh at 272.
Singh had five birdies and an eagle on the back nine. He caught Ogilvie on the treacherous 15th, an island hole with sand traps on two sides.
Mickelson was tied for second going into the final round. Playing in the same group as Ogilvie, he made birdies on 15, 16, and 18 for a 4-under 68.
Ogilvie moved up to the PGA Tour for the second time this year. His best previous finish was a tie for fourth at the 2000 Fed Ex Classic.
Ogilvie's putter, which got him the lead earlier in the week, wasn't as dependable on Monday. He missed birdie putts on 14 and 15.
