The world number one is only the fourth player after Steve Davis, Stephen Hendry and Ronnie O’Sullivan to claim back-to-back titles in the modern era.
Mark Selby defended his World Championship title with a stunning comeback to beat John Higgins 18-15 and secure his third crown in four years.
A dreadful collapse for Higgins means having come through a comfortable semi-final against Barry Hawkins, he was initially at ease against Selby, stroking in a 141 break which equalled O’Sullivan’s effort in 2012 as the best break recorded in a World Championship final.
And Selby was out of sorts during Sunday’s play at the Crucible, missing straightforward opportunities in the reds to hand his opponent the initiative.
But the 33-year-old, who was named ‘The Torturer’ by Ronnie O’Sullivan for his gritty victory in 2014 from 10-5 behind, showed similar uncompromising characteristics with a ruthless display.
In the final session, the pre-match favourite made breaks of 71, 70 and a 131 clearance following the contentious call in the 31st frame.
