John Higgins secured a 10-7 lead over defending champion Mark Selby on day one of the World Championship final at the Crucible Theatre.
Scotland’s four-time champion made a superb 141 clearance – the joint-highest break in a world final – on his way to taking a commanding 10-4 lead.
World number one Selby finally found his form and breaks of 121 and 81 helped him win the last three frames.
The best-of-35 final resumes on Monday at 14:00 BST and is live on BBC Two.
The 41-year-old Higgins, who beat Selby in the 2007 final, is aiming to become the oldest winner since 45-year-old Welshman Ray Reardon triumphed in 1978.
Two-time champion Selby, 33, is bidding to become only the fourth player – after Stephen Hendry, Steve Davis and Ronnie O’Sullivan – to win consecutive world titles in the modern era.
