- Welshman comes from behind for 10-8 victory
- Xiao Guodong completes 10-4 win over Matthew Selt
Mark Williams was forced to dredge up every inch of his Crucible experience to sink rising Chinese star Wu Yize 10-8 and book his place in the last 16 of the World Snooker Championship for the 22nd time in his career.
Williams, who turned 50 last month, delivered two near-faultless final frames to hold off his opponent, who had missed a golden chance to seize a 9-7 advantage when he missed a frame-ball red with the rest.
