Former winner Scott Waites came close to a shock exit from the BDO World Championship at the hands of debutant Sam Hewson at Lakeside.
The 2013 champion was beaten at the first hurdle last year by Alan Norris and had to battle back from a set down to beat the 21-year-old.
Number 15 seed Darryl Fitton, who has reached the semi-finals twice, won seven consecutive legs to beat Paul Jennings 3-0.
Scotland captain Ross Montgomery is also through, with the 11th seed beating Pip Blackwell 3-1.
