Young Jordan Spieth capped off a second consecutive runaway victory with a six-under 66 on Sunday to win the Hero World Challenge by a massive 10 strokes at Isleworth.
The 21-year-old Spieth, who closed with an eight-under 63 to win last week's Australian Open by six shots for his first win of the year, collected a million prize and satisfied a goal by winning his second title of 2014.
It was a bravura performance by the precocious Texan, who finished on 26-under-par 262 to shatter the tournament record of 22-under 266 set by host Tiger Woods in 2007.
"I think last week was a big boost of confidence," said Spieth, who will move up to ninth in the world rankings from 11th.
"I'm very, very pleased with the year and how it came to a close."
Woods, meanwhile, failed on his modest goal of escaping last place in the 18-man event when he suffered another embarrassing chipping display, taking a triple-bogey at the par-five 13th.
He posted a 72 for even-par 288 to tie Hunter Mahan for bottom of the table, but later pronounced his return to competition after a long absence from back injuries as an overall success.
"I made some progress," said Woods, who is also working on a swing change. "I hadn't played in four months and I'm in absolutely no pain, which is nice.
"To be able to go all out on some of these drives like I did this week really enforces that what I'm doing is the right thing for my body."
Henrik Stenson of Sweden finished a distant second, 10 shots behind Spieth after shooting a 69 for 272.
Another shot back were Patrick Reed and fellow American Keegan Bradley, who exchanged his belly putter for a conventional one this week ahead of the 2016 ban on anchored putters.
The brilliant Spieth ended a stretch of 43 holes without a bogey with a double bogey at the par-four 14th, the only blemish on a card that featured six birdies and an eagle.
"This is the best that I've played in my life," said Spieth, who won a college tournament at Isleworth three years ago by eight strokes.
"And I got to say the same thing last week in a media tent in Australia."
