Barry Hawkins survived a stirring fightback from Ryan Day to win the Ladbrokes World Grand Prix on Sunday night, live on ITV4.
Hawkins, the world number 12, raced into a 9-3 lead at Preston's Guild Hall courtesy of five century breaks.
But Welshman Day forced his way back into the best-of-19 final by winning four successive frames.
A relieved Hawkins however, held his nerve in the 17th frame to pot the black and clinch the title 10-7 to claim the £100,000 top prize.

Neil Robertson failed to build on his superb defeat of Ronnie O'Sullivan as Barry Hawkins claimed a place in the semi-finals of the Ladbrokes World Grand Prix.
Robertson eased past five-time world champion O'Sullivan 4-1 in their second-round meeting on Thursday afternoon but was unable to replicate that form later as he lost 4-2 to Hawkins in the last eight.
Hawkins, who beat Judd Trump 4-1 earlier in the day in Preston, did not trail against the Australian after taking the first frame with a break of 81 following a Robertson mistake.
Robertson levelled but Hawkins took the next two in scrappy circumstances. Hawkins missed a chance to settle the match in the fifth frame, and Robertson replied with a frame-winning run of 51, but he made no mistake in the sixth, securing victory with an 85 break.
Hawkins told ITV Sport: "I wouldn't say it was a solid performance, we both missed a few, but I'm pleased to get past Neil and be in the semi-final.
"I finished off well, I needed to win that frame, as I've started to get a name for myself for collapsing after getting in front."
Liang Wenbo claimed his place in the last four with a hard-fought 4-3 victory over Joe Perry.
Wenbo rattled in two centuries but was never able to pull clear as the pair traded frames throughout.

Professional snooker player Leo Fernandez has been banned for 15 months after admitting spot-fixing.
The Irishman received the ban and was ordered to pay £2,000 costs after a hearing on his 40th birthday on Tuesday relating to the first foul of his World Championship first qualifying round match in April.
He had been provisionally suspended on May 27 and cannot now return to the sport until August 2017.
Fernandez has been an intermittent presence on the professional tour since first qualifying in 2007, though a run to the quarter-finals of last year's Haining Open on the Asian Tour had earned him a return.
Ding Junhui reached his first World Championship final in record-setting style as he saw off Alan McManus at the Crucible.
China's number-one player fired his seventh century of the semi-final, a classy 123, and completed a 17-11 victory over Scottish veteran McManus.
Before Ding's masterclass, the record in Sheffield stood at six centuries in a match, achieved by Mark Selby and Ronnie O'Sullivan, but he has rewritten that corner of the history books and also becomes Asia's first World Championship finalist, a landmark moment for the sport.
His earlier tons in the match were 100, 131, 100, 128, 138 and 113, and in a startling run of scoring he also fired breaks of 84, 62, 90, 97, 80 and 60.
Ronnie O'Sullivan has admitted he's "not really bothered" about the World Championship after winning two titles already this year.Read the full story ›
Barry Hearn has backed Ronnie O'Sullivan's decision to turn down a maximum break opportunity at the Welsh Open this week.
O'Sullivan potted an easier pink en route to his eventual clearance of 146 and said afterwards he thought the £12,000 total prize money on offer was "too cheap".
Hearn, chairman of snooker's world governing body, said O'Sullivan had not broken any rules and conceded his unpredictability helps give the sport a higher profile.
Hearn told BBC Radio Five Live: "Some have said he has brought the game into disrepute but Ronnie brings the game into fine repute.
"In his little head, he thought it would be funny. He is quite dry. The 147 is the pinnacle but Ronnie has made loads of them (13), he has got loads of money.
"He is the biggest character in the sport. When he breaks the rules, he gets punished, in this case, it was his choice.
"Without personality and characters, sport dies. O'Sullivan is the biggest character in the sport."
O'Sullivan had made a break of 80 he asked an official and members of the commentary box what the prize was for a maximum break.
To the groans of some in the audience, he then proceeded to play for the pink instead of an eminently available black off the 14th red before clearing the rest of the balls.
O'Sullivan said later: "I could have done it, but I didn't think the prize was worthy of a 147, so I've tried to let it build up until it's worthy and then go for it."
Ronnie O'Sullivan is in line for his sixth Masters title after he dominated the opening session of Sunday's final against Barry Hawkins.
Playing in his first major tournament in nine months, O'Sullivan was in impressive form at Alexandra Palace in London as he bounced back from losing the opening frame to lead 7-1 before the evening session.
In their 10 previous encounters Hawkins has won only once, in their first meeting during the Scottish Open in 2002.
Australia's Neil Robertson completed a 147 maximum break to secure a £44,000 bonus as he built a lead in the UK Championship snooker final.
Robertson punched the air in delight and received a standing ovation from the York Barbican Centre crowd after he potted the final black to take a 4-2 advantage against China's Liang Wenbo.
Wenbo also enjoyed the moment, clapping and then hugging his opponent, who now has managed three maximums in his career.
Ronnie O'Sullivan has announced his intention to play in the Masters next month after skipping the UK Championship.
O'Sullivan said two weeks ago his decision to pass up the chance to defend his UK title in York was to try "different things" and that he no longer desired the pressure of being snooker's "top man".
But the 39-year-old announced on Twitter that he will play in the 16-man Masters, which will be held at Alexandra Palace in January.
Looking forward to playing the Masters so thought we'd do the announcement from the bar! Get it done. ? https://t.co/LWdEWYr2iJ
O'Sullivan has won the sport's most famous non-ranking event on five occasions, most famously as a 19-year-old in 1995.
His last competitive match was at the World Championship in April, when he lost in the quarter-final to eventual champion Stuart Bingham.
