Ronnie O’Sullivan reeled off five frames in succession to beat Zhou Yuelong 6-2 and reach the quarter-finals of the Players Championship.

Competing for the first time since withdrawing from the Wales Open due to anxiety, O’Sullivan was far from his fluent best in the early stages but improved markedly after the interval in Telford.

The seven-time world champion produced a superb total clearance of 136 in the sixth frame, won the next after Zhou inexplicably missed a simple green and wrapped up the win with a run of 73.

O’Sullivan was in no mood to give any insight into his performance, however, telling ITV4: “I don’t assess my performances really, I make that a golden rule. Bit of match practice, take what I can from the tour and move on.

“I’m just trying to get away with playing as least as I can, I feel happier doing that.

“This is all icing on the cake for me, whatever I get off this tour. I’ve got my exhibitions, my ambassador work and that’s my main thing – I just fit in a few tournaments around that.”

Mark Allen earlier made three consecutive centuries, including a tournament record 146, on his way to an impressive 6-3 win over three-time world champion Mark Williams.

Allen followed his 146 in the opening frame with breaks of 112 and 102, restricting Williams to a solitary point in the process, and also made breaks of 94, 70 and 68 to ease into the quarter-finals.

“Any win against Mark is a good win, but to play like that and score like that, that’s what I needed because I haven’t been doing that much,” Allen told ITV4.

“I’m not going to go into it, but I am trying something a bit different this week so we’ll see if it works. It is a timing issue that I feel like I’ve had in recent months so the technical change I’ve made I’m hoping will correct that.

“I started the match as good as you could with three centuries and disappointed not to make four, but that’s the way you need to play.

“I lost a few (against Mark) early on when I first turned pro and I think that’s nine of the last 10 I’ve won now so maybe that’s in his head a little bit as well.”

Allen will play Gary Wilson in the quarter-finals after he came from 2-0 down to beat Hossein Vafaei 6-4, the Welsh Open winner sealing victory with a break of 95.

Ali Carter will take on Judd Trump after breaks of 116, 97, 66 and 69 helped secure a 6-2 victory over Tom Ford.

Ronnie O’Sullivan has once again questioned his snooker future after squeezing into the quarter-finals of the World Grand Prix in Leicester with a 4-3 win over Zhou Yuelong.

Just four days after his controversial eighth Masters triumph over Ali Carter, O’Sullivan said he was getting no enjoyment from continuing to move through tournaments with comparative ease.

O’Sullivan told ITV4: “I’ve got to really consider whether I can carry on feeling how I’m feeling out there – I just don’t get any enjoyment from the way I’m hitting the ball.

“I feel like it’s just hard work, I haven’t a clue where the balls are going, and a lot of it’s just guess-work.

“The worst thing is you’re winning bloody tournaments as well. If I was getting pumped every round playing like that it would be an easy decision to make.”

O’Sullivan had eased into a two-frame lead with breaks of 67 and 107 and looked set to extend that advantage before he missed a red to the top pocket to run aground on a break of 50 in the next.

Yet to beat O’Sullivan in their five previous encounters, Zhou responded in style with a 76 to narrow the deficit, then a nerveless 102 to level the match and confirm the change in momentum.

Zhou, who had recovered from a three-frame deficit to push O’Sullivan to a final frame decider in their most recent meeting at the UK Championship in December, responded to falling behind again with breaks of 65 and 66 to force the decider.

The Chinese player got in first and potted a red and black, but missed his chance to the middle and O’Sullivan swept up with aplomb with a nerveless 90 to seal another seemingly unsatisfactory win.

“It’s been happening like this for 25 or 30 years, so it’s nothing new,” O’Sullivan added.

“It’s the only thing I’ve known and it’s hard not to do this because it’s my job, it’s all I know, so I’ve struggled through it.

“But I can’t accept bad cueing, I’d rather cue well and lose than cue awful and win tournaments. I get no satisfaction out of it, I really don’t.”

O’Sullivan will face Gary Wilson in the last eight after the reigning Northern Ireland Open champion saw off Tom Ford 4-2.

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.”
