Ronnie O'Sullivan finished off with a brilliant 147 break as he stormed into the quarter-finals of the Coral UK Championship with a 6-0 demolition of Matthew Selt.
O'Sullivan's maximum at the end of the fourth-round clash at York's Barbican Centre was the 109th in snooker history and the 13th of the Englishman's career - improving his own all-time record.
The 38-year-old, who had a scare when the final blue wobbled in the jaws of the middle pocket before dropping, is set to earn £44,000 for the break, which is the first of the tournament.
Making the achievement even more remarkable is that the five-time world champion is playing on a broken left ankle, sustained while out running in Essex last week.
Such was the pain of the injury that O'Sullivan suggested after his first-round victory he might have to withdraw from the tournament if there was no improvement.
However, O'Sullivan played through the pain and on Thursday rewarded the watching public - and even fellow players Stephen Maguire and David Morris who briefly stopped their fourth-round encounter on the neighbouring table to follow the action - to another potting masterclass.
O'Sullivan, who rattled in four half-century breaks as well as his maximum as he swept aside Selt, will play Anthony McGill for a place in the semi-finals as he continues his hunt for a fifth UK Championship crown, and first since 2007.
Elsewhere Kilkenny's Morris exited the tournament as he went down 6-3 to Maguire.
Maguire got off to a fine start, racing into a 3-1 lead over Morris before the Irishman rallied to draw level at three frames a piece.
However he was unable to sustain that level and Maguire turned on the style to win the next three frames and book his place in the quarter-finals.
Earlier in the day Marco Fu and Shaun Murphy served up another dramatic encounter at the before the Hong Kong potter sealed his place in the quarter-finals with a 6-5 win.
Murphy beat Fu 10-9 in a tense 2008 final and the pair went the distance again on Thursday, with the match being decided on the final black at York's Barbican Centre.
The Englishman had looked on course to seal a place in the last eight when he built a 5-3 lead - helped by a superb 137 in the fifth frame - but Fu battled back to level things up at 5-5.
Murphy again seemed to have the edge in the final frame but, after compiling a break of 54, he snookered himself on the final yellow and Fu did not let his opportunity slip, the 36-year-old potting all the colours to take the decider 74-62.
Judd Trump, the 2011 champion, also took his place in the last eight during Thursday's afternoon session after overcoming veteran Rod Lawler 6-3.
The Bristolian started off with a 102 break in the opener but then lost the next two frames as the world number 66 briefly gave his 25-year-old opponent a scare.
However, Trump responded by winning five of the next six frames after that, sealing the win with another century - 112 - in the ninth to set up a quarter-final clash with Mark Davis.
