"I played in six final groups previous year, majority coming from behind, and I probably just pushed a little too hard trying to catch up, trying to play a ideal first six holes and it didn't really work out for me", he said.
Schauffele's charge continued with a hole-out for eagle on the short par-4 12th to get within one shot of the lead, and he closed with four birdies over his final five holes to post his final score of 23-under 269.
Tournament of Champions victor Xander Schauffele still considers himself an underdog despite a stunning come-from-behind victory in Hawaii. Woodland responded with an 11-foot birdie of his own at 17, but after Schauffele birdied the par-five finishing hole with two putts from 12 feet, Woodland couldn't make his own 10-foot birdie putt at 18 to force a playoff. His shot of the day came on the par-5 15th when he drained a 63-foot eagle putt to create separation between him and the field.
He missed it but his birdie was enough to earn a fourth PGA Tour victory and a rise to No.6 in the world rankings.
A subdued Rory McIlroy said he would remain patient after another disappointing final round scuppered his chances of victory at the Sentry Tournament of Champions in Hawaii on Sunday.
"Well it means I get to come back, which is even better", Schauffele said of qualifying for next year's Tournament of Champions with the victory. "It was nice to see that long one go in on the par five there on the back, nice to finish with a birdie here on 18".
"It was a frustrating final day; the putts didn't really go in", said Leishman, who will rise two spots to No.18 on the world rankings.
Rami Malek & 'Bohemian Rhapsody' Win Big at Golden Globes 2019!
Director Peter Farrelly said the win was beyond anything he and his team imagined when they embarked on the film. It was one of the Golden Globes' biggest surprises. "I'm kind of really gob-smacked by this, " said Burnett.
"I don't think it will ever be easy because I still believe I was playing well enough to shoot 66 today", Woodland said.
That gave overnight leader Gary Woodland a number to shoot for, and the former Kansas star got within one shot with a birdie on No. 17.
McIlroy's third round was bogey-free but while he was seven-under over the back nine for his opening 36-holes he was just one-under over the same nine holes on day three and that was thanks to a birdie at the 14th and with the Ulsterman failing to hole an eight-footer for birdie at the par-5 18th.
"So, it could have been a couple better but then in saying that I had a good save at two, a good save at 16 so it could have been a little worse".
"It's just something I am going to have to persist with, keep putting myself in these situations", he said on Sunday. I got that phone call late last night.
Defending champion Dustin Johnson tied for fourth with Australia's Marc Leishman and Northern Ireland's Rory McIlroy at 15 under.
His deficit increased to six when he bogeyed the first hole at Kapalua's Plantation course.
