Ronnie O'Sullivan in more trouble after obscene hand gesture
Ronnie O'Sullivan found himself in more bother at the World Championship in Sheffield after being warned for making a rude gesture during his second-round match against Matthew Stevens.
On the table the five-time world champion enjoyed a successful day, firing two rapid centuries in establishing a 12-4 lead, having finished the opening session 5-3 ahead.
He needs just one more in today's closing session to the match to reach the quarter-finals.
But O'Sullivan was also spoken to by the referee Olivier Marteel towards the end of the afternoon session - and warned about his behaviour.
Marteel approached O'Sullivan as he walked to the table when Stevens missed a red, telling O'Sullivan he had noticed his hand gesture, which was thought to have been self-directed.
O'Sullivan avoided a fine in the first round when he briefly played without shoes after a new pair proved uncomfortable, breaking the rules but not sufficiently to warrant any punishment, after he accepted a substitute pair of size eights, loaned by tournament director Mike Ganley.
The warning from Marteel could be the end of yesterday's matter. Yet any repeat of the incident in the same match would see O'Sullivan docked a frame, a tournament spokesman confirmed.
Meanwhile, Ali Carter continued to struggle in his match against Australia's Neil Robertson.
The 35-year-old from Essex, who trailed 6-2 following Saturday's opening session, won the first frame of the day but lost the next five.
A finish with a session to spare was possible when Robertson led 11-3, but Carter took the last two frames of the day to avoid that indignity and trail 11-5 overnight.
Judd Trump leads Marco Fu 10-6 in another game to be finished today, with Trump posting a final-frame 75 to resist Fu's admirable comeback.
A fine 111 had put Trump 9-3 ahead but Fu dug deep to leave a little more to play for.
2005 winner Shaun Murphy only needs one frame today to book his quarter-final place as he holds a comfortable 12-4 overnight lead over Joe Perry.
Murphy, catching the eye in his red ensemble, transferred his dashing appearance to the table as he rattled in scores of 57, 50 and 88, although Perry at least kept his head above water for another day, highlighting with a 131 while he also returned two breaks of 74.
