Wales' Ryan Day, the 32-year-old who lost World Championship quarter-finals in 2008 and 2009, will have a third bite at a last-eight tussle.
Day knocked out Ding Junhui in the first round and completed a 13-7 win over Ding's 21-year-old Chinese compatriot Cao Yupeng.
He awaits the winner of the match between fellow Welshman Matthew Stevens and England's Barry Hawkins, having finished off Cao with his second century of the evening.
Day, who has fallen from sixth to 35th in the rankings, won all four frames and said: "I've only got to the quarters here before. It's a big match for me next and if I can win it’s new territory.
"I know if I win the next match it all changes and becomes a one-table set-up, and everyone wants to play on that stage.
"If I can play like I did in the last four frames consistently, I know I can beat anybody."
Judd Trump, last year's runner-up who struggled with food poisoning in his opening win over Dominic Dale earlier in the week, reported healthy for his second-round clash with Ali Carter but fell 5-3 behind.
They resume on Sunday afternoon and play to a finish on Monday.
