Mark Williams and Zhao Xintong played out a compelling opening day of their World Snooker Championship final at the Crucible as the Chinese star built a healthy lead overnight of 11-6.
At 50 years of age, Williams is the oldest Crucible finalist in history as he tries to claim a fourth world title, 25 years after his first. Meanwhile, Zhao is 22 years his junior and the 28-year-old is the youngest World Championship finalist since 2011.
