Defending champion Ronnie O'Sullivan had his hopes of a record-equalling seventh world title shattered in the second round by Anthony McGill on Friday. McGill triumphed 13-12 in the final frame at the Crucible in Sheffield after O'Sullivan had fought back from 10-5 down to lead 11-10 and then 12-11. The Scottish player, ranked 16 and who was a semi-finalist in the last world championship, held his nerve with an 85-point clearance in the decider. dj
