World champion Ronnie O'Sullivan plans to put an end to Chinese teenager Ding Junhai's record-breaking run at the Masters at Wembley here on Friday. O'Sullivan booked his quarter-final place with a 6-3 win over Graeme Dott and insists he is ready to face the young Chinese as he chases his third trophy of the season. "Ive come up against a lot of unknown quantities in my career so Im used to it," said OSullivan. "Im used to people expecting me to win matches and win tournaments, that comes with being world number one and world champion. Im there to be shot down and Friday is just another game."

The 17-year-old Ding, from Shanghai, became the youngest quarter-finalist in the history of the Masters when he knocked-out former world champion Ken Doherty 6-1.
