Ronnie O'Sullivan once again made snooker history after crafting the sport's highest ever break, a stunning 153, in his quarter-final with Ryan Day at the World Open in Yushan.

The Rocket has achieved a perfect 147 break a record 17 times previously. However, this contribution was aided by a free ball and included 14 blacks with two pinks, before he deposited all of the colours to end on 153. That left the Englishman two points shy of the highest possible run of 155.

The only ever break to have exceeded 147 prior to this was a 148 made by Jamie Burnett at 2004 UK Championship qualifying. O'Sullivan's incredible run this afternoon eclipses that and puts him in line for the £5,000 high break prize.

Earlier this season the seven-time World Champion became only the second player in snooker history to make two maximum 147 breaks in a single match, achieving the feat in his Saudi Arabia Snooker Masters semi-final with Chris Wakelin. He followed on from Jackson Page, who made two maximums in the penultimate round of 2025 World Championship qualifying.

Further runs of 62, 110, 103 and 95 saw him run out a 5-0 victor and book a place in the semi-finals against Wu Yize.
