This time last year eventual champion Ronnie O'Sullivan was the first player to reach the semi-finals with a 13-3 demolition of a stoical Anthony Hamilton. Displaying a devastating show of strength the Rocket rattled in four centuries on his way to victory. Hamilton, already 7-1 adrift by the end of the morning session did manage to claw back two of the evening frames. But it proved to be a mission impossible with O'Sullivan sealing the match in the 16th with a session to spare. Hazel Irvine introduces today's quarter-final action, with Clive Everton ,
