BBC Sport at The Crucible
Ronnie O'Sullivan completed a ruthless demolition of Stephen Hendry as he stormed into the final with a 17-4 win.
Hendry was facing an insurmountable task even before a ball was potted after trailing by a massive 13-3 at the end of Friday's second session.
O'Sullivan put himself on the brink of victory by winning three of the four frames before the mid-session interval.
The Rocket then wrapped up the biggest ever semi-final win in Crucible history with a break of 79 when play resumed.
It was one of the most clinical displays ever at the World Championship, with seven-time champion Hendry reduced to the role of a mere spectator for long periods.
O'Sullivan's only possible cause for disappointment was that he failed to turn several breaks in the 80s and 90s into centuries.
The Englishman's play was almost error-free from the first frame and he put Hendry under tremendous pressure by capitalising on even the smallest mistakes by the Scot.
And it makes O'Sullivan red-hot favourite to lift a second World title and add to his crown from 2001.
