Ronnie on course for world title hat-trick

Ronnie O'Sullivan continued his march towards a third successive World Championship title last night while Mark Selby and Neil Robertson's semi-final was squarely in the balance after the first session.

O'Sullivan opened up a 6-2 lead over Barry Hawkins and Selby was on course to do likewise against an out-of-sorts Robertson, only for the world number one to add to his historic century of centuries and close to 5-3.
