Ronnie O'Sullivan whitewashed Mark Williams 6-0 at the Manchester International Conference Centre to claim his fifth title of the season.
It took just 73 minutes for O'Sullivan to beat his Welsh rival win the final of the Betfred.com Premier League.
O'Sullivan warmed up for the clash with Williams by crushing Stephen Hendry 5-0 in the semi-finals on Friday.
In the final, he made a 134 total clearance to edge Marco Fu's 133 as the highest break of the event.
O'Sullivan, who has already won the Grand Prix, Welsh Open, Wembley Masters and Irish Masters, earned £50,000 for his win and tops the end-of-season money list with £380,250.
Williams, who won £25,000 as runner-up in Manchester, was second on the list with £281,800.
O'Sullivan was delighted with his victory and heaped praise on the groundbreaking competition, which introduced a unique 25 second shot-clock.
"This has been my favourite tournament of the year. The World Snooker Association could learn something from the way it's been run," said O'Sullivan.
"There have been no slow frames with people falling asleep."
The world number one lost 13-11 to Peter Ebdon in the quarter-finals of the Embassy World Championship at the Crucible 10 days ago, having fallen victim to his opponent's controversial go-slow tactics.
Williams is still waiting to lift his first trophy since the 2003 LG Cup.
"The first couple of frames could have gone either way but after that he just blew me away," said the Welshman.
