MARK SELBY produced a vintage display to sweep past Ronnie O’Sullivan 6-0 and secure his place in the semi-finals of the Players Championship in Telford.

World number one O’Sullivan had looked pretty much untouchable this season, with four major ranking titles already.

However, it was Selby, himself a four-time world champion, who produced a high-quality display with half-century breaks or higher in five frames to end O’Sullivan’s 16-match unbeaten run.

There had been a controversial start to the match in the opening frame when referee Desislava Bozhilova failed to warn O’Sullivan after a second missed attempt when he could see one side of a red.

She swiftly realised her error, apologised to both players and promptly informed the world number one he would forfeit the frame if he did not hit a red with his next shot.

O’Sullivan’s response was to smash into the reds, opening up the table which allowed Selby to eventually clinch the frame with a break of 65.

Selby, who will play either China’s Zhang Anda or John Higgins in the semi-finals, soon built early momentum following a clearance of 91. After O’Sullivan did not make the most of a chance in the third, another break of 81 further extended his advantage.

It was turning into a vintage display from the Jester from Leicester, who produced another fine break of 105 to go into the mid-session interval in complete control at 4-0.

Following the resumption, O’Sullivan continued to make some wayward shots, going in off a red and into the top pocket as Selby went on to take the fifth frame with a 59 clearance.

The Rocket finally kicked into gear in the next frame with a break of 58, only to run out of position and then see an attempted safety shot back up the table edge the green to leave a red on.

Following a couple of tense exchanges, Selby sunk a long red at pace into the bottom left corner and then dropped in a deft final red after O’Sullivan had left it just over the pocket before clearing the colours to take the frame 70-58, completing a memorable win.

“To beat Ronnie in any tournament is a great scoreline, to beat him in the way I did, I am very, very pleased. It was more or less faultless,” Selby said on ITV4.

“It is a huge game and if you can’t get up for matches like that, you might as well put your cue away.

“I felt confident I could win, because if you don’t then more often than not the scoreline will be the other way.

“The biggest thing for me is that when I am not winning I try to tweak things, but the two performances I have put in here have proved to me that what I am doing now is what I need to carry on doing, whether I win or lose.”
