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.
