Ronnie O’Sullivan has created more snooker history by making the sport’s highest-ever professional break with a 153 at the World Open in Yushan.

Seven-time world champion O’Sullivan set the new record in the opening frame of his quarter-final with Ryan Day to pave the way for a dominant 5-0 victory.

The 50-year-old left Day in a snooker at the start of the frame and the Welshman’s failure to escape gifted O’Sullivan a free ball.

He potted the green as the 16th red before adding his opening black and then reeling off 15 reds, 13 further blacks and two pinks before clearing the final six colours to reach 153.

It breaks the previous record for the highest professional break – a 148 set by Jamie Burnett at the UK Championship qualifiers in 2004.

“Just want to say a big shoutout to all the people who have been messaging me, congratulating me on the 153,” O’Sullivan said in a video posted on X.

“It was a pretty cool moment, really happy to do it. Thank you to everyone out there that has supported me.”

O’Sullivan will face China’s Wu Yize in the semi-finals after he stormed past Northern Ireland’s Mark Allen with a 5-1 win.
