Scott had the low round of the tournament with eight birdies in his round of 64.
That is what McDowell, Mickelson and Stricker would have needed to have any chance of catching Woods. As he did early in the third round, McDowell gave it his best shot, only to have Woods answer on every occasion.
McDowell two-putted for birdie on the par-five opening hole as Woods blasted a shot from a buried lie at the back of the green well past the pin and off the green. He had to chip close just to save par. McDowell hit his approach on the second hole to seven feet and looked as if he might pick up another shot.
In what might have been the most significant putt Woods made, he buried an 18-footer for birdie.
That is how it went all weekend. Woods never gave anyone a chance, and he did not give anyone much hope. His lead was back to four shots, he hit an eight-iron to four feet on the par-three fourth hole, and no one seriously challenged him the rest of the way.
Mickelson hit a 200-yard shot into the breeze and over the water to a foot for a tap-in birdie on the par-five eighth to get within four shots with 10 holes to play. However, he missed far too many short putts, making bogey on the ninth and 11th holes to fall too far back to matter.
That allowed another easy walk up the 18th hole for Woods to collect another WGC title, another seven-figure check and offer another reminder that he is closer than ever to getting back to the top of golf.
Woods now has won over US$24 million in the WGCs alone since the series began in 1999, winning 43 percent of the tournaments. This was his 76th career win on tour, leaving him six short of the record 82 wins by Sam Snead.
