Ryan Searle became the fifth player to top their PDC Home Tour group with a perfect record as he surged into the next round as James Wade endured a night to forget.
Heavy Metal, who won his maiden PDC title by defeating Michael van Gerwen earlier this season, is among the fastest improving players on the circuit despite his vision impairment so his Group Six success will come as little surprise.
The 32-year-old joins Jamie Lewis, Luke Woodhouse, Dave Chisnall, Geert Nentjes and Nick Kenny in the next round, with the latter four of those players also progressing with a 100% record.
Wade, winner of nine PDC premier titles, was the headline act in Group Six but Searle showed the kind of form that helped him reach round three of the 2019 World Championship, where he led 3-1 against Gary Anderson before falling to a 4-3 defeat.
Searle opened up with a one-sided 5-1 victory over Andy Boulton before taking on Wade in a potential group decider.
However, Searle improved as the evening went on and rattled in five maximums, averaging 100.6 to see off Wade in eight legs.
'Heavy Metal' was straight into his final match against Adrian Gray, with his place in the second round at stake, and eased to a 5-2 triumph courtesy of a 103.3 average.
Boulton and Wade, who both defeated Gray earlier in the evening, battled out for the second place in the final contest of the match and the former prevailed with a whitewash result.
