Australia's Neil Robertson withstood a superb fightback from Andrew Higginson to win the Welsh Open final 9-8.
Robertson has been a model of consistency this week
Robertson went into the match as a heavy favourite against the unranked Englishman and raced into a 6-2 lead.
But Higginson hit back with a series of big breaks to move to 8-6 ahead and within sight of a stunning win.
However, Grand Prix winner Robertson held his nerve with breaks of 92 and 59 to force a deciding frame and took it with two visits to the table.
I can't grumble, the week has been beyond my wildest dreams
"At 6-2 Andrew's arm was loose," said Robertson afterwards. "He probably thought he had nothing to lose and the way he played in the next six frames was breathtaking.
"He was incredible and when he did miss the odd ball he seemed to get away with it. I knew I just had to remain patient and believe in myself.
"I wasn't super-panicky but of course I was getting a little anxious. It was just a matter of getting a chance and thankfully I got it."
606 DEBATE: Comment on Robertson's final win
Higginson - who turned professional in 1996 - was not too downhearted after becoming the first unranked player since Terry Griffiths in the 1979 World Championship to appear in the final of a ranking event.
"I've really enjoyed this and it is an experience I'll never forget," he said. "I can't grumble, the week has been beyond my wildest dreams."
He added: "I don't want to be a one-hit wonder. The tournament has really opened my eyes to what I can achieve.
"I thought it was my time but Neil did really well to catch me in the end."
