SHEFFIELD: Ronnie O'Sullivan entered the record books on Tuesday when he became the first player to record two 147 breaks at the Crucible Theatre.
His latest maximum break, during the world championship first-round clash with Hong Kong's Marco Fu, comes six years after his first at the same venue.
O'Sullivan cleared the table in the seventh frame, a feat that could earn him £169,000 (US$266,600) £147,000 for the maximum and £22,000 for the top break if it is not equalled during the tournament.
It was an otherwise disappointing opening session for O'Sullivan, who won the world title two years ago, with Fu posting a surprise 6-3 lead at the close.
Fu now needs four more frames to record a shock win when play resumes yesterday afternoon.
World number four John Higgins was forced to work hard to beat qualifier Ian McCulloch in his first-round match.
McCulloch knocked in breaks of 100 and 94 to cut Higgins' lead to just two frames at 9-7. But a missed yellow in the 17th frame allowed Higgins to clear up and complete a 10-7 win.
Higgins will face lowly-ranked qualifier Sean Storey in the second round, but he insists the tie is not a mere formality.
Thailand's James Wattana has a 6-3 lead over Jimmy White in their first round encounter. Tony Drago from Malta, leads Joe Swail 5-4 . Reuters
