During the UK Championship, we're looking back at some of the most memorable moments on this day in the history of Snooker. Today, we reflect on Ronnie O'Sullivan's memorable 13th maximum break at the 2014 UK Championship...
O'Sullivan had already made headlines at the York Barbican Centre for his decision to play in the tournament despite breaking his ankle whilst running the previous week.
Having safely navigated his way past Daniel Wells, Peter Lines and Ben Woollaston in the opening three rounds of Snooker's second-most prestigious ranking event, he dominated proceedings against Matthew Selt in the Last 16.
Breaks of 76, 61, 52 and 89 had fired the Rocket into a commanding 5-0 lead and one frame away from a place in the quarter-finals.
However, he saved the best until last - knocking in 15 reds followed by blacks with pinpoint position along the way.
It looked as though the chance of a 13th 147 had gone, before the blue just dropped in after appearing to stay out when it rattled in the jaws.
Despite that scare, O'Sullivan held himself together by sinking the pink and black to extend his lead at the top of the all-time list with the 109th maximum break in the history of Snooker.
