This is the fourth time Woods has reached the championship match, but this week at Dove Mountain forced him to play more holes (88) in the five matches to get to the finals.
It looked like it would be a short day of work.
Woods lead was the second-largest margin after the morning 18 in the final. David Toms was 6 up over Chris DiMarco in 2005. Woods had seven birdies and shot 66, including a bogey on the 18th, his first in 50 holes.
Cink, who had birdie or eagle on 33 of 81 holes, made only three birdies for a 71.
Woods birdied the first two holes, making a 25-footer at No. 2 for a lead he did not come close to surrendering in the morning round.
This looks like Torrey Pines, said Cinks caddie, Frank Williams.
They played in the last round of the Buick Invitational last month, when Woods had an eight-shot lead and still made it entertaining with birdie putts of 40 feet and 60 feet.
Cink was on the defensive, usually the first to putt, and he quickly dug himself a hole in the high desert.
He found a bunker off the tee on the par-5 fifth, laid up into the rough and did not give himself a good look at birdie, losing another hole when Woods made his putt from 6 feet. Cink also made a mistake on the par-3 eighth, opting to putt from 6 feet off the edge of the green, and the ball got hung up in hairy grass and stopped 12 feet short of the cup, leading to bogey.
Woods was 4 up at the turn, and it looked like a rout when his wedge on the 11th spun back to 4 feet, and Cink missed the green to the right, taking two chips to reach the green.
Outside the ropes, NBC Sports was scrambling. The network finally got Woods in the final, and it looked as though its four-hour coverage might have two hours of championship golf, if that much.
Cink didnt win his first hole until No. 12, a shot of desperation. From just short of the green, having to carry a line over two humps that could have sent the ball off the green, he played a pitch to near perfection for birdie.
Then on 16th, he holed a 25-foot birdie putt to cut Woods lead to 3 up.
The par-5 17th was pivotal. Another win'even a halve'could have given Cink loads of momentum heading to lunch. Woods, however, hit driver off the fairway to just short of the green and executive a brilliant pitch that skipped four times and stopped 2 1/2 feet next to the cup for a birdie to restore his lead to 4 up.
Cink squandered another chance at the 18th with a three-putt from just off the back of the green. Woods twice hit into a bunker for his first bogey in 50 holes at Dove Mountain, but still had a big cushion.
Woods was going for his 15th title in 26 starts at the World Golf Championships, and his fourth consecutive PGA TOUR victory. He also was trying to move past Arnold Palmer into fourth place alone on the PGA TOUR's career list with his 63rd victory.
