Robertson gets title defence off to flyer
The Australian raced to a 5-1 victory over Michael Holt, which included a break of 130, to set up a last-eight clash with another Englishman, Shaun Murphy.
Murphy secured his place with a 5-2 third round win over 17-year-old Chinese player Zhao Xintong.
Liang Wenbo, who dispensed with world champion Mark Selby in round two, could not repeat the feat as he was comprehensively beaten 5-2 by Joe Perry.
Perry’s reward is a head-to-head with Finland’s Robin Hull, a 5-1 winner over China’s Cao Yupeng.
Marco Fu edged his way to a quarter-final against Barry Hawkins after being taken all the way by Stuart Bingham.
Fu made two centuries on the way to a 5-4 victory which was sealed 78-34 in the final frame.
Hawkins made short work of seeing off Scotland’s Alan McManus with a best of 138 in a 5-2 win.
But fellow Scot Stephen Maguire fared rather better as he whitewashed Judd Trump to set up a showdown with Martin Gould.
Maguire rattled off five frames on the trot to claim victory, although Gould had to work a little harder to see off Ryan Day 5-3.
