Ronnie O’Sullivan won a tense deciding frame against China’s Wu Yize at the World Open in Yushan to reach his 66th ranking final.

It came the day after he produced the sport’s highest-ever professional break of 153 in his 5-0 quarter-final victory over Welshman Ryan Day.

The seven-time world champion was never behind against Wu but struggled to break clear of the world number 11 before finally completing a 6-5 victory.

Wu had the first chance in the decider, opening a decent lead with a break of 43, but 50-year-old O’Sullivan punished a poor safety shot by sinking a long red then held his nerve with a clearance of 89.

The Englishman has not won a ranking event since beating Judd Trump to claim victory at the World Grand Prix in January 2024.
