World Open snooker: Mark Allen beats Neil Robertson

Allen, the world number 11, was trailing 4-2, but overcame the Australian with consecutive breaks of 71, 105 and 75 to progress to the last eight.

Sky Bet now make Allen 5/1 to win the tournament.

"It shows my game is in good shape, that even when I was struggling at 4-2 behind, I still managed to come through," Allen told World Snooker.

"It's a little bit of a bonus to still be in the tournament, and hopefully I have three tough matches in front of me, but if I play as well I did towards the end I think I have a good chance."

Awaiting Allen for a place in the semi-finals will be England's David Gilbert following his 5-2 victory over John Higgins.

Four-time world champion Higgins had never lost to Gilbert, but he was no match for the Englishman who sealed his place in the quarter-finals by winning the last four frames.

"It's nice to finally get a win over John," Gilbert added. "He is a great player so it is good to have that on my CV."

There were also wins on Thursday for Anthony McGill, Luca Brecel, Li Hang, Ding Junhui, Mark Williams and Kyren Wilson.
