LONDON - China's top player Ding Junhui failed to reach the quarterfinals of the Snooker World Championship as the world No 11 was beaten by five-time world champion Ronnie O'Sullivan 13-10 on Sunday.

Ding and O'Sullivan came into Sunday's final session tied at 8-8. O'Sullivan started the session by winning two frames in a row and kept his leading position all along.

"In the first two sessions, Ronnie missed a lot of blacks or pinks off the spot and I took those chances. I played well, but today wasn't as good as the first two sessions. Sometimes I need to score heavily and I didn't do that well enough," the 33-year-old Ding told the World Snooker Tour website.

O'Sullivan will face Mark Williams in the quarterfinals and a win will put the Rocket into the semifinals for the first time since 2014.

Meanwhile, Neil Robertson has set up a clash with Mark Selby after the Australian ace defeated Barry Hawkins 13-9 in the second round.

Kyren Wilson will challenge reigning world champion Judd Trump after knocking Martin Gould out 13-9.
