Snooker: Ronnie O'Sullivan began his campaign for a third World Championship title by taking a narrow 5-4 lead over teenage Chinese debutant Liu Chuang.
O'Sullivan showed flashes of his brilliant best as he took the opening two frames with breaks of 76 and 87, and won the third after a protracted safety battle on the yellow.
However, 17-year-old Chuang deservedly got on the board with a break of 92 and won the next two frames to level at 3-3.
O'Sullivan edged clear with a 57 clearance but Chuang made it 4-4 and O'Sullivan was grateful to win a tight ninth frame ahead of tomorrow's final session.
