China's Ding Junhui suffered a shock defeat 13-7 to Barry Hawkins at the quarterfinals of the World Snooker championship on Wednesday.

Hawkins, who stunned world No. 1 Mark Selby in the second round, will next take on Ricky Walden or Michael White for a place in the final.

Ding, ranked ninth in the world, trailed Hawkins 3-5 in the first session and 7-9 in the second Tuesday night. He struggled in the third and made errors constantly while he 14th-ranked Hawkins took command and wasted no chances.

"It's unbelievable," Hawkins said. "I felt pretty good. I've been trying so hard for so long just to make some kind of breakthrough and I managed to do it this year in Australia (by winning). I've been pretty consistent through most of this year but to come here and get to the one table set-up is like a dream come true."

Ding said: "I don't like morning sessions because I can't sleep properly the night before. Sometimes something bad that's happened keeps battering away in your mind so you can't sleep.

"Some players get help from experienced players but I haven't got anyone to help me so I have to do everything myself. I like to listen to people who will tell me if I'm doing something bad, that would be a big help for me.

"Barry took his chances and made big breaks and every frame his safety was good. Mine wasn't as good because I left him a lot of chances to take. Sometimes you need to be very strong but that's what experience will do for me. I need to learn what to do in each session."
