Selby 2-6 Xiao
Wu Yize will now play Xiao Guodong in the quarter-finals on Thursday after Xiao played superbly to defeat three-time champion Mark Selby in the evening session.
Xiao, 36, made breaks of 95, 62, 76 and 77 as he won the opening four frames, with Selby’s highest break only being 21.
But the four-time world champion threatened a superb comeback as he made breaks of 101 and 76 to bring it back to 2-4.
Xiao had not potted a ball in 46 minutes but then did excellently to make a break of 118 to move one frame away from victory, which he clinched by edging a scrappy eighth frame.
