Three-time winner Mark Selby cruised through to the last eight of the Masters with a 6-1 victory over Robert Milkins at Alexandra Palace.

World number five Selby, who won the tournament in 2008, 2010 and 2013, raced into a 4-0 lead and although Milkins briefly stemmed the tide by taking the fifth frame, the result was never in doubt.

Selby produced a 119-break in the second frame of the evening match to assume control and compiled four more frame-winning half-century breaks to seal a convincing win.

The four-time world champion made scores of 70 and 74 in the final two frames to stay on course for a sixth appearance in the Masters final.

Mark Allen had earlier conjured a break of 86 in the final-frame decider to oust John Higgins and advance to the quarter-finals.

A week after 16-year-old Luke Littler thrilled during the World Darts Championship it was two old-timers that were starring at Ally Pally.

Higgins, a two-time champion, looked to be in control as back-to-back 80-plus breaks put him 3-1 up.

But world number three Allen won the next two scrappy frames, thanks to some wayward potting by Higgins to draw level.

The Northern Irishman had to wait until frame seven to make his first half-century break as he took the lead for the first time and then a sumptuous 123 clearance – the best of the match – put him one frame away.

Higgins had been looking beaten for the previous 30 minutes but summoned his renowned fighting spirit to reduce the deficit after winning the tactical battle and then sent it to a decider with a 61 break.

But hopes of a comeback were put to bed as Allen produced his decisive break to set up a last-eight tie with Selby.

He said: “It wasn’t a phenomenal contest, we were both a bit edgy, but any win against John is a good win so I will take it.

“Strangely I didn’t feel too bad in the last frame because 5-3 to 5-5 I didn’t feel like I’d done much wrong.

“I missed two really tricky shots, so I was looking forward to getting a chance and when John missed that long red I was fearing the worst but I got another chance and I made the most of it.”

Downbeat Ronnie O’Sullivan has warned he will continue “stinking out gaffes” after he limped into the quarter-finals of the UK Snooker Championship with a 6-5 win over Robert Milkins in York.

O’Sullivan, who is playing in trainers due to suffering from the heel injury plantar fasciitis, made his frustration clear as he almost blew a 5-3 lead before rallying to earn a last-eight slot against Zhou Yuelong.

“I don’t understand how this game works,” shrugged O’Sullivan. “I gave up a long time ago. I just keep turning up and stinking out gaffes. I stunk it out today and I’ll stink it out tomorrow. You’ll have to get a mask to watch me play.”

Despite hitting a 142 in frame five, O’Sullivan, who is aiming for a record eighth UK crown, was far from his best, and expressed his irritation after serving up one of three glorious opportunities for Milkins in the decider by dropping his cue onto the table.

But Milkins, whose solitary win over O’Sullivan in 11 previous attempts had come at the single-frame Shoot-Out in 2002, failed to capitalise, missing a pink then a simple red to middle, before finally dangling a red over the bottom pocket that effectively sealed his fate.

The win extended O’Sullivan’s stay in the city for at least one more day, ring-fencing enough ranking points to give him hope of preserving his status prior to the festive period, when he intends to skip the Scottish Open then jet off for a Christmas Day exhibition in Macau.

“I just don’t want it bad enough any more,” added O’Sullivan. “I’m having to dig deep. When I was younger I didn’t have to dig deep, I was so hungry, and now I’m just thinking I don’t really care.

“It’s nice if I get through but I don’t actually want to work that hard. That’s why I like doing my exhibitions, my own shows in China. It’s still competitive but it doesn’t matter if you win or lose, you can have a drink after and a bite to eat.

“Competitive sport is hard, it’s not just about how good you are but how much you want it. I still want to play, I still like the lifestyle and the travelling. But I’m not going to kill myself out there, it’s not worth it.”

O’Sullivan’s judgement was off from the start, allowing Milkins, whose career has been revitalised since his first ranking title win at the Welsh Open in February which sent him into the world’s top 16 for the first time, to capitalise and establish a 2-0 lead.

It should have got even better for Milkins, who had a glorious chance to go 3-0 in front before a simple missed red allowed O’Sullivan to produce a quickfire response of 86, followed by a 53 in the fourth frame which took him into the interval level at 2-2.

A brilliant 142 total clearance sent O’Sullivan in front for the first time, and another Milkins error in the next, when he broken down on a black on 52, allowed O’Sullivan to sweep up to go 4-2 in front.

The game’s momentum continued to swing, as Milkins reduced the deficit with a coolly-dispatched 91, then O’Sullivan responded with an 83 to edge one frame from victory.

Milkins hit back again, with a superb 120 before O’Sullivan missed a simple missed blue in the next, showing more frustration with a rash attempt to escape from a snooker that served up his opponent with the simplest of chances to pull level.

Milkins could hardly have hoped for a better chance to end his career-long drought over multi-frame matches, but the nerves clearly got the better of him, and he was inevitably made to pay for his misses as O’Sullivan rallied to clinch a thoroughly underwhelming win.

John Higgins’ hopes of setting up another showdown with his long-time rival were dashed when he fell 6-3 to Zhou in another erratic affair, sending the Chinese player into the quarter-finals for only the second time in his career.

Zhou was whitewashed in both previous meetings with O’Sullivan in York, in 2018 and in last year’s last 16, but said: “I have beaten some good players this week and it has given me confidence that this time against Ronnie it will be different.”
