Lewis goes into his match with the Dutchman knowing that he will progress through to the final eight if he avoids defeat, and the Stoke-based thrower has taken confidence from his form over the past four weeks.
The 28-year-old told PDC.tv: "I've given myself a great chance by going unbeaten for four weeks.
"I'm very proud because my form was shocking at the start of the Premier League, but I can feel it coming back in patches.
"I've got no choice against Raymond - if you don't play your best you're in trouble. We always have great games but I think I'll get the job done."
