A dazzling closing 63 gave Tiger Woods an amazing fifth successive victory as he claimed the Deutsche Bank Championship.
Three behind Vijay Singh overnight, the world number one took the title in Boston by two from the Fijian and so continued his summer domination of the sport.
After missing the halfway cut at the US Open in his first appearance since the death of his father, Woods has followed a second place at the Western Open with wins in the Open, Buick Open, US PGA Championship, Bridgestone World Championship and now this.
The 30-year-old turned his three-shot deficit into a three-stroke lead by going to the turn in 30, grabbing eagles at the second and seventh and birdies on the third and fifth.
Singh, who had charged clear of the field with his US Tour best 61 in the third round, cut the gap back to two on the 12th and looked set to be only one behind when he almost pitched in at the 15th.
But Woods responded with a 14-footer for a matching birdie three and rolled home a 25-foot putt two holes later.
"I just kept thinking that if Vijay shot something in the high 60s, I figured mid-60s would either get me in a play-off or win it,'' Woods said.
"And that was what I had in mind and I was able to actually go a little bit lower than that.''
Singh beat Woods in the same tournament in 2003 to interrupt Woods' reign as world number one.
Woods added: "Well, I hit it good today. I got off to a quick start. I didn't think I would get all of them back within the first three holes, but the par-five number playing downwind, with the length that Vijay and I both have - put the ball in the fairway and you can have an iron to the green.
"And he missed the fairway there and I made eagle there and just got all the momentum. I got back two shots instead of basically feeling all square.
"I made a nice putt at the third and then all of a sudden I had all the momentum on my side and just tried to continue doing what I was doing. Hitting the ball well and making some putts." PA
