However, Williams’ compatriot Matthew Stevens is out, beaten 4-3 by Englishman Martin Gould.

Michael White faces China’s Liang Wenbo and Ryan Day battles Mark Allen.
Williams revealed after the match that he is trying to play as fast as possible.
“My main aim was to play as fast as I can and stop thinking about stuff I’ve been thinking about,” he told BBC Radio Wales.
“Today I potted quite a few long ones and made a lot of good breaks.
“Whether or not it’ll continue tomorrow I don’t know, but I’m certainly going to go out with the same mindset.”
Earlier, England’s Joe Perry enjoyed a 4-2 victory over Ken Doherty, while Ben Woollaston edged out Anthony Hamilton in a deciding frame.
