Mark Selby and Kyren Wilson marched into the semi-finals of the World Championship with commanding victories over Mark Williams and Neil Robertson.
Selby thrashed fellow three-time champion Williams 13-3, to win with a session to spare.
And Wilson reeled off five frames in a row to seal a 13-8 victory over 2010 winner Robertson.
Selby will play Anthony McGill or Stuart Bingham next, while Wilson will face Judd Trump or Shaun Murphy.
Leading 6-2 overnight, Selby looked back to his best as he made breaks of 96, 58 and 66 en route to winning the opening four frames of the day.
Williams, who last won the world title in 2018, briefly rallied with a 79 before Selby completed his win.
“He totally outplayed me,” Williams said. “I thought he was brilliant from start to finish. His potting was better and his safety was better, which is not that easy to do.
“If Judd Trump, Kyren Wilson and the others are all playing well and Selby is playing well, he is in a different class to the lot of them.
“If he keeps playing like that he is better than anyone else in the game and I think he will win it.”
Meanwhile, Wilson reached his third Crucible semi-final after dispatching one of the pre-tournament favourites in Australia’s Robertson.
With the match delicately poised at 8-8 overnight Wilson, who beat Judd Trump at the same stage last year, opened up with a superb break of 133 before moving 11-8 ahead.
Last year’s beaten finalist also won a scrappy 20th frame to leave Robertson needing to win all five remaining frames, and a composed break of 84 saw Wilson confirm a comprehensive win.
The two remaining best-of-25 quarter-finals will be played to a conclusion on Wednesday.
McGill begins with a 9-7 lead against 2015 champion Bingham, while former winners Trump and Murphy are tied 4-4.
