Ken Doherty has made it through to the quarter-finals of the Welsh Open in Newport after beating Tom Ford 4-3.

The Dubliner was 2-0 up but a 101 break in the sixth frame brought the English player level at 3-3.

The 1997 World Champion held his nerve to win the decider 71-23 to continue his good form after beating John Higgins in the previous round. 

Doherty will face Stuart Bingham in the last eight. 

Pankaj Advani made history as a 4-1 victory over Graeme Dott saw him became the first Indian player to reach the quarter-finals of a world ranking event.

Advani, the multiple world billiards champion playing as a newcomer on the main snooker tour this season, went 2-0 up in the second-round match in Newport with breaks of 63 and 73.

Dott pulled the third frame back, but Advani subsequently wrapped things up, finishing with a superb break of 100.

The 27-year-old from Pune has now defeated two former world champions at this tournament, having knocked out Shaun Murphy in round one.

"I am surprising myself with this run but I'm just going with the flow and trying to keep winning," Advani told

"It's exciting to be playing against the best in the world, at the top level and under the best conditions."

Advani's last-eight opponent will be world number two Judd Trump, who comfortably saw off Andrew Higginson 4-1.

"It's nice to see someone from overseas do well and hopefully it will help us get some tournaments in India," Trump said of Advani.

"I hope he bottles it under pressure tomorrow but I don't think he will."

Defending champion Ding Junhui is also through having beaten Mark Allen 4-2.

China's Ding will face the winner of this evening's contest between Sam Baird and Robert Milkins for a place in the semi-finals.

There will be no home representation in the last eight, with Welshman Matthew Stevens losing 4-2 to Stephen Maguire, who came from behind to win the last three frames.

Maguire's quarter-final opponent will be the victor in tonight's Alan McManus-Joe Perry match.
