Ding Junhui suffered 5-1 defeat by Jin Long at Haikou World Open

Jin, the 30-year-old from Jinzhou, Liaoning Province, took full advantage of a below-par Ding, growing in confidence as the match progressed.

Jin won some close frames in the early stages and reached the interval with a 3-1 lead. A break of 76 gave him the fifth frame and two visits in the sixth secured him a famous victory over the player who had won the Welsh Open just nine days earlier.

"I made some mistakes but had a little more luck and Ding didn’t grab his chances," said Jin.

The Bristol potter took control of the match from the outset and an out-of-sorts Higginson was never at the races. Trump’s top break was a 111 in the third frame.

"I think I played pretty well and I know Andrew didn’t play that well so that made it pretty easy for me," said Trump.

"I felt good out there and there were a lot of people. It was quite noisy and I didn’t expect that many people to be honest. I had a lot of support so I was happy."

John Higgins completed a scrappy 5-3 victory over Marco Fu to also move into the last 16.

The reigning world champion looked in for an easy afternoon’s work as he led 3-1 at the mid-session interval, and a run of 70 in the fifth frame put him one away from victory.

In the next, on 60 though, Higgins missed a red into the corner pocket and Fu completed a run of 40 to steal the frame and keep his hopes alive.

With Higgins looking a little tentative, Fu took the next with a break of 63 before the Scotsman secured the win with a 77 break. He can now look forward to facing Martin Gould or Jamie Cope in the next round.

"Marco was a tough match as the Chinese people wanted to see him win so I was happy to beat him this time. My confidence is way down at the moment and you have to start winning matches to get it back."

Meanwhile, former world champions Shaun Murphy and Graeme Dott also went through at the expense of Ricky Walden (5-3) and Barry Hawkins (5-2) respectively.
