Ronnie O'Sullivan continues to test officialdom
RONNIE O'SULLIVAN could face punishment after placing his chalk on the table in the World Championship at the Crucible.
O'Sullivan, 39, broke snooker rules by lining up a shot with the chalk but was not reprimanded by the referee during his match against Stuart Bingham.
A World Snooker spokesman said it will investigate the incident.
Referee Terry Camilleri should have called a foul when O'Sullivan placed his chalk on the table to line up a shot, as snooker rules state a seven-point penalty will be awarded to the opponent if a player 'uses any object to measure gaps or distance'. It is not O'Sullivan's first controversy of this championship.
He escaped a fine after briefly playing in his socks in his first-round win over qualifier Craig Steadman. He also came close to snapping his cue during his second-round match against Matthew Stevens.
Judd Trump is on course for his third World Championship semi-final appearance after firstly dominating the best part of the morning session against third seed Ding Junhui and then continuing to tag on the frames last night, including a break of 98 in the 16th frame, to open up a 12-4 advantage in the best of 25.
World number six Trump laid down a marker ahead of the tournament with victory over Ronnie O'Sullivan in the World Grand Prix final and he reproduced that form to leave Ding battling to overcome a 6-2 deficit after the morning frames.
Ding barely made an impression early on as Trump stormed into a 4-0 lead, underlining his dominance with a break of 94 in the fourth frame.
Trump picked up where he left off after the mid-session interval with a century break and overcame a deficit in the sixth frame to continue his stunning start. Ding finally got off the mark in the seventh and entered the evening session with feint hope after claiming back-to-back frames.
