Judd Trump was at his unstoppable best as he beat India's Aditya Mehta 6-0 to reach the International Championship quarter-finals in Chengdu.

The 2011 UK champion started as he meant to continue, taking the first frame and pulling two clear with a break of 98.

Mehta continued to make errors and two scoring visits in frame four - the second a 62 kick-started by an outrageous long red with the white in the jaws of the green pocket - put the Bristolian 4-0 up.

They had played for little more than 40 minutes before heading to the interval - at which point world number one Mark Selby was still in his first frame against Ricky Walden following a long quest for a snooker.

Good safety brought Mehta back from a 62-point deficit in the first frame back, but he undid his good work by leaving an easy brown and Trump cleared to lead 5-0 before clinching a whitewash win in the next frame.

Trump will face Mark Allen, who avenged his first-round defeat at this year's World Championship against China's Cao Yupeng.

Allen accused his opponent of dishonesty after that match, claiming Cao failed to declare an illegal push shot when leading 5-4.

The Northern Irishman further alleged that "blatant cheating" might be "a bit of a trait for the Chinese players". He issued an apology for his remarks but, quoted in this morning's Sun, said: "I still feel I was right about the incident in question."

He led 3-1 at today's mid-session interval, after a half-century to come from 46-9 behind in the fourth frame, and repeated that scoreline after the interval to seal a 6-2 win.

Shaun Murphy held off a fightback from home favourite Ding Junhui to win 6-4.

Breaks of 59, 52, 103 and 78 saw Murphy into a 4-1 lead but Ding surged back to 4-4, the highlight being a 66 in frame seven.

But Murphy's second century, 108, took him ahead again and he took the next in three visits.

Earlier, Neil Robertson showed glimpses of hisbest snooker in a 6-2 win over Matthew Stevens.

Robertson led 2-1 after a break of 100 and finally took a long fourth frame by potting the pink and black after missing two chances.

A 63 made it 4-1 and, after Stevens pulled one back, the Australian sealed victory with breaks of 75 and 85.

He will face 14-year-old home sensation Lu Haotian, the youngest ever winner of a match on the professional tour, who made the most of his walkover against the absent Ronnie O'Sullivan by upsetting world number 23 Dominic Dale.

Lu came from 3-1 down and the players traded frames from 3-3, the youngster holding his nerve at the tail end of each of the final two frames for a memorable win.

China Open winner Peter Ebdon continued his impressive form in Asia with a straightforward 6-1 dismissal of Scotland's Steven Maguire.

Hong Kong's Marco Fu eventually won 6-4 against Mark Davis in a match which was suspended from the early session and concluded after Trump's rapid win.

Fu, leading 5-4 when the players were hauled off, took the first frame back to deny Davis a place in the world's top 16 ahead of the UK Championship and the Masters.

The pair's lethargy was matched by Walden and Selby, who had only just resumed after their interval - with Walden leading 4-0 - as the rest of the day's action concluded.

Selby finally got on the board in frame five, after Walden this time played on in search of snookers, but Walden responded with a 54 to end another tortuous frame and move within one of victory.

Selby prolonged the match still further with a century and then pulled back to 5-3, but Walden finally got over the line in the next. He now faces Ebdon in the last eight.

Allen, meanwhile, was in no mood to be conciliatory after beating Cao, tweeting: "Never, I repeat NEVER have I wanted to win a match as bad as I did today!!! Job done. Now lets all move on!!"
