Ronnie O'Sullivan appears set to end Mark Selby's hold over him in major finals after a devastating 7-1 opening session to their Masters showpiece.
The world champion has been in brilliant form all week at Alexandra Palace and his quarter-final whitewash of Ricky Walden is already being considered one of the great performances.
Few expected him to take Selby to town, though, considering the Leicester cueman has got the better of O'Sullivan in last-frame deciders of three of their finals.
He will have to go some to reach the heights of Antwerp, Wales and the 2010 Masters here, though, with O'Sullivan leading by six frames.
In a record 10th final of the invitational event, O'Sullivan had four of those frames in the bag by the mid-session interval, with scores of 97, 70 and 96 going alongside a scrappy fourth.
The break did little to help Selby, with O'Sullivan taking the fifth after initially breaking down when he missed a blue designed to develop the pack.
Selby took some confidence from that and clawed back to 5-1, ruling out a whitewash - Steve Davis handed out the only Masters final one of those in 1988 - before O'Sullivan pinched the seventh.
He was 35 behind with 35 left when Selby made a hash of a safety and after clearing up, took the respotted black with a gutsy pot to the left middle. The final frame of the afternoon duly followed, with the 38-year-old outscoring his opponent by a total of 612 to 223.
