He was joined in the last 16 by Adrian Lewis, who had to come from behind to record a 6-4 victory over Mensur Suljovic.
Jelle Klaasen produced the surprise result of the night after he won the final four legs to beat Wes Newton 6-4, with Kevin Painter moving past John Part by the same scoreline.
Mervyn King and Andy Hamilton came through last-leg deciders against Ronnie Baxter and Terry Jenkins respectively, while there were also successes for Justin Pipe and Paul Nicholson.
