Neil Robertson held off a mini-fightback from Jack Lisowski to comfortably reach the semi-finals of the Tour Championship at Celtic Manor.
Holding a commanding 6-2 lead from the afternoon session, Robertson saw his advantage trimmed as Lisowski won the opening two frames of the evening session.
But the Australian quickly regained the upper hand and won 10-5 to advance to the last eight, where he will face either Mark Selby or Kyren Wilson.
'Nice to be part of history' - Robertson proud of achievements in snooker
Their best-of-19 quarter-final takes place on Wednesday, with the final last eight meeting between world No 1 Judd Trump and Barry Hawkins on Thursday. Ronnie O'Sullivan awaits the winner of that match.
While Robertson had been in sparkling form during the opening session against Lisowski, it looked like he was going to be made to work harder to wrap up the win.
Lisowski won the opening frame of the evening session and then added another with a break of 95.
Robertson replied with a half-century break and then restored his four-frame lead before a 121 took him closer to victory.
Lisowski hit back with a brilliant century break of his own - a 129 in less than nine minutes - but Robertson took the next frame to seal the win.
