Mark Williams will attempt to upset world number one Neil Robertson once again after booking a second-round meeting with the Australian at the China Open.
Two-time world champion Williams overcame Anthony McGill 5-3 in Beijing on Tuesday to set-up the clash with Robertson.
Williams has fallen out of the top-16, and will need to qualify for the world championships later this month, but was victorious when he last played Robertson at the Welsh Open earlier this year.
"I'll just try my best tomorrow," Williams told www.worldsnooker.com.
"Neil is a top player and world number one so it will be a tough game for me. If you are going to do well in competitions you have to beat players like that.
"Obviously it's the toughest draw I can get and hopefully I can play well and give him a good game."
Mark Selby overcame a late-night workout to before eventually beating world number 98 Stuart Carrington 5-3.
It was a case of last-man standing for the world number two, who was a runner-up in Beijing 12 months ago, after Carrington ensured they remained at the table long after the matches around them had finished.
Shaun Murphy beat Jamie Cope 5-1 as he aims to win back-to-back world rankings titles, after tasting success at the Haikou World Open.
"To win back to back tournaments here is very difficult," he said.
"Of course Ding Junhui has done it already, he's won four tournaments this season so it can be done. All I can do is to concentrate on my next game."
Local hopeful Ding easily won through to the last-32 as he cast aside John Astley 5-1, while fellow top-10 players Judd Trump, Marco Fu and John Higgins also progressed.
