‘Just chill’ – O’Sullivan and referee clash for second time during tense quarter-final

“Ronnie O’Sullivan urged referee Desislava Bozhilova to “chill” in the 21st frame of his quarter-final against Stuart Bingham. Fans watching the match on the other side of the arena were returning from the mid-session interval as O’Sullivan sized up a red with the pair locked at 10-10. The seven-time world champion went back to his chair until the melee eased but eventually lost the frame.”
