China's Ding Junhui staged a dramatic comeback from 9-12 down to defeat England's Stuart Bingham 13-12 on Monday and reach the World championship quarterfinals for the first time.
The Chinese star has won the UK Championship and Masters events in his career but has struggled in Sheffield, despite it being his adopted home city.
Ding will next face England's Mark Selby who defeated seven-time champion Stephen Hendry.
Breaks of 92 and 114 had seen Ding cut the deficit to 12-11 in the evening session and he opened the next with a 58.
Bingham had a chance to clear up, but was unlucky to snooker himself on 34, and eventually lost it on the colours.
In the decider, Bingham made 30, then Ding responded with 55.
It came down to a safety battle on the last two reds, and, trapped in a snooker behind the pink, Bingham fouled and left his opponent a clear chance. Ding added 10 points and sealed victory with a long green.
O'Sullivan moves up
Former champion Ronnie O'Sullivan set up a quarterfinal clash with John Higgins.
O'Sullivan converted a 9-7 two-session lead over Shaun Murphy into a 13-10 triumph, scoring early breaks of 128 and 119 and then surviving a scare when his opponent began to fight back.
“No matter how badly I've played, I've still come to win,” said O'Sullivan.
“Making the quarterfinals, it's not about that. It's about being the best, being the winner.”
Hendry admitted that retirement is an option after he was crushed 13-4 by Selby.
“I'll decide in the summer,” said the 42-year-old Scot. “I've still got the game but I haven't got the self-belief to play with these guys.”
Hendry is nowhere near the force which has brought him almost nine million pounds in prize money, 36 ranking event titles and eight years as World No. 1.
But he last won a ranking event six years ago and has not triumphed at the UK Championship, Masters or World Championship — the three most prestigious events on the calendar — this century.
“If someone said you could have 26 years here, win it seven times and be in two more finals, make two 147s, I think most people would take that,” said the emotional Scot. — AFP
