Ronnie O’Sullivan stands just one win away from a sixth World Championship title after he produced his brilliant best to beat Mark Selby.

The five-times world champion produced one of his greatest comebacks of all time as he recovered from 16-14 behind to win a final frame decider in breathtaking fashion.

Victory means O’Sullivan will play in his seventh World Championship final this weekend – his last appearance coming six years ago when he lost to Selby.

He will face Kyren Wilson who also won an extraordinary final frame decider in the afternoon after winning what was described as the best frame the sport has ever seen.

And maybe O’Sullivan’s dramatic comeback will go down as one of snooker’s best ever comebacks after the Rocket appeared to be all at sea while trailing 15-14 – hitting some shots in frustration and looking like he was lost by one of the game’s greatest tacticians.

When snookered he recklessly smashed the cueball to all parts in an attempt to get out of the situation but without success – leaving the snooker world puzzled as to his shot selections.

But what followed was sporting brilliance at its best – as O’Sullivan went from the ridiculous to the sublime in a matter of minutes.

Needing to win all remaining three frames, O’Sullivan produced a sensational seven-minute break of 138 to reduce his arrears to a single frame.

And just minutes later he produced yet another fantastic display of attacking snooker and cueball control as a break of 71 forced the match into a decider.

From nowhere, Selby’s control of the game had vanished.

And a break of 64 helped O’Sullivan and some magnificent safety play saw him complete the 17-16 win – on what was described as one of snooker;’s best ever days of action.
