Defending champion Mark Selby made history at the UK Championship on Saturday when he completed the 100th maximum break in professional snooker during his winning semi-final against Ricky Walden.
The Englishman's 147 will earn him a prize of STG55,000 ($A100,000) in addition to a STG4,000 ($A7,250) bonus for recording the highest break in the tournament - provided his achievement is not matched.
His victory set up a meeting with Australian world No.1 Neil Robertson in Sunday's final.
Selby made the break in the seventh frame at the Barbican Centre in the northern English city of York, playing a superb pot on the brown and then nudging an extremely awkward black into the middle pocket to complete the feat.
"Up until the green I had played pretty much the perfect break, but then there was some tension because the brown only went to one pocket and it was hard work from then on," he said.
"It was a great moment, but I am still involved in a tough semi-final, which isn't over."
The break gave Selby a 5-2 lead in the best-of-17-frames encounter and he ended the first session 6-2 up.
Earlier, Robertson survived a stirring comeback from England's Stuart Bingham.
The Australian led 8-3, putting him within one frame of victory, only for Bingham to launch a superb fightback and level.
However, Robertson completed a gripping 9-8 victory.
"I've improved with every performance as the tournament's gone on," said Robertson. "I've still got a few gears to come, so hopefully my best snooker's to come in the final."
