John Higgins restricted Mark Selby to just seven points as he thrashed the three-time world champion 6-0 in the quarter-finals of the Players Championship.
Higgins made breaks of 60, 70 and 63 in winning the first three frames in Milton Keynes without conceding a single point.
Selby managed six points in the next frame but lost it 75-6 and Higgins wrapped up an extraordinarily one-sided contest with a century in frame five and breaks of 49 and 60 in the sixth.
The four-time world champion, who will face Kyren Wilson in the semi-finals on Saturday, also competed a clean sweep over Welsh Open winner Jordan Brown in the first round and told ITV4: "I can't play any better than the two matches I've played so far.
"I felt in control and I couldn't believe Mark's only scored seven points because I'm too busy zoned in in the match. I can't believe I've done that to someone like Mark Selby, it's unreal.
"It was as close to perfect that I could ever play so to do it against Mark is a feather in my cap. I'm over the moon."
Selby admitted he was outplayed by Higgins, adding: "I didn't really do hardly anything wrong.
"The first three frames I didn't have one chance at a pot. John played outstanding and shut me out from start to finish. It's not as if I was missing ball after ball and giving John clear-cut chances."
