World number two Mark Selby booked his place in the Australian Open quarter-finals with a 5-1 victory over China's Zhang Anda.
He reeled off breaks of 69, 71, 76 and 90 and now meets fellow Englishman Mark Davis in Bendigo.
Selby, 30, said: "I scored well every time I got a chance. The first frame was important because he had me in trouble but I fluked a red and won it.
"If he had won that it might have been a different match."
World number one and home favourite Neil Robertson went through with a 5-3 win against Stuart Bingham and now faces Joe Perry.

Defending champion and 2013 World Championship runner-up Barry Hawkins was a quarter-final casualty, going down 5-4 to Tom Ford.
Ford now faces Robert Milkins, who was a 5-2 winner against Rory McLeod.
