Ronnie O’Sullivan repelled the determined challenge of Ding Junhui to become the oldest winner of the UK Snooker Championship in York, 30 years after he claimed his first title at the tournament at the age of 17.

O’Sullivan, who turns 48 on Tuesday, triumphed 10-7 after a heavyweight battle with his Chinese opponent, sealing a record-extending eighth UK crown with an exhibition-style finish of 129 amid raucous scenes at the Barbican.

Hauled back from 4-1 and 7-5 leads by Ding, who like O’Sullivan won his first UK title as a teenager in 2005, the world number one dug deep when it mattered and consecutive breaks of 100 and 74 set him up for his final flourish.

But amid the inevitable uproar, O’Sullivan cut a somewhat underwhelmed figure, admitting his latest win lacked the “buzz” of some of his earlier successes, and said he had even found himself struggling for motivation as the opening session loomed.

“I’m not sitting here with a massive grin and super-excited,” said O’Sullivan. “I just go through the motions a lot of the time.

“It’s great to win and I give my best when I’m out there and I want to win, but it’s not the same excitement as years ago when I was winning my first world and UK and Masters titles, and you’re buzzing.

“Don’t get me wrong, it’s still a nice feeling and a job well done, but I get more of a buzz from going for a run in the morning or having breakfast with my mate.

“I don’t actually feel like ever playing. Once you get down there you think you’re glad you’ve done it, but even in this match today I was thinking I didn’t feel like it, I’d rather sit on my bed and watch a bit of Netflix. I feel like that a lot of the time.”

It was an admirable effort from the Chinese player, who had clambered off his sick bed to sink defending champion Mark Allen on the opening day having seriously considered withdrawing from the tournament.

But ultimately O’Sullivan, who had seldom been required to find his best form during his journey through the tournament, had just enough to leave Ding contemplating a second consecutive final defeat.

Ding had clawed back to level at 4-4 at the end of an absorbing opening session, after a series of costly errors gifted O’Sullivan the early advantage.

Three times the 36-year-old blew early frame-winning opportunities to fall 3-0 then 4-1 behind before belatedly stirring to reel off three frames in a row including breaks of 114 and 70.

O’Sullivan wasted no time in re-establishing his lead in the first frame of the evening with a break of 84, but there was a hint of impatience in the next when he opted not to play on despite trailing by 51 and only requiring one snooker.

Ding appeared intent on pressing home his advantage but was punished for taking on some risky long shots in the next two frames, O’Sullivan edging ahead again with breaks of 40 and 87, then emerging from a scrappy spell in the next to reach the interval 7-5 in front.

A hard-earned 58 from Ding brought him back within one frame before a magnificent 104, his second century of the final, pulled him level again.

Anything Ding could do, O’Sullivan could do too, and the momentum swung back in the direction of the world champion in the next frame when he responded with a century of his own, a 100, his first of the final.

A brilliant pink from O’Sullivan set him up to move one frame from victory with a break of 74, and he completed his win in his own irresistible fashion with his second three-figure finish.

Ding, who was also beaten in last year’s final by Allen, reflected: “The first half was disappointing because I had a chance to win more frames but 4-4 wasn’t too bad because I was 4-1 down. I came back to 7-7 but he played so well.

“All I could do was play good safety and make breaks. He just pushed me to make mistakes and it’s all I can do – I can’t do anything else out there.”
