Reigning world champion Mark Williams goes through to the second round of the snooker World Championship with a 10-7 win over Martin Gould
Last year’s final saw Mark Williams win his third World Championship - 15 years after his last - by holding off John Higgins' stunning fightback in a classic Crucible final.
Williams, 43, won 18-16 to become the oldest champion since fellow Welshman Ray Reardon, who was 45 in 1978.
