Ronnie O'Sullivan fired a 147 to seal a 13-7 victory over Mark Williams and a place in the last eight of the World Championship.
The 32-year-old was narrowly leading Williams 9-7 going into the final session at the Crucible in Sheffield on Monday afternoon, however he went further ahead with breaks of 71, 60 and 100.
O'Sullivan then stylishly secured the game in the 20th frame with his ninth maximum of his career and his third at the Crucible, to earn himself a quarter-final place against Liang Wenbo and a cheque for £157,000 - £147,000 for the maximum plus £10,000 for the highest break - as long as no other player repeats the feat during the rest of the tournament.
"As soon as I got on the first red I thought that I had to go for the 147," O'Sullivan told BBC Sport.
"Obviously it's more important to win the game but that money gives me a few options in the summer. I'll be getting a Bentley Convertible now - I've been dying to get one!
"The difference between this season and the last 13 seasons is that I've stumbled across a couple of things and kept my discipline with it and stayed patient.
"So I've never hit disastrous standards - before as soon as it went wrong I just wanted to get out of there."
