The second day of European Darts Matchplay action in Trier saw 10 seeded players suffer upsets, including top seed Gerwyn Price, World Grand Prix winner Jonny Clayton, and Premier League runner-up Joe Cullen.
Price's recent struggles continued on Saturday evening as he was bested by Rowby-John Rodriguez.
The Welshman managed to win just two sets against the dominant Austrian, who booked his place in the third round with a 6-2 victory.
Clayton suffered a similar fate, with the world No.8 struggling to cope with Scott Williams, who secured a 6-4 upset to progress. Cullen started brightly in his match against Ian White, but after missing several chances to end the match, the 51-year-old punished him in a deciding leg.
Daryl Gurney, Martin Schindler and Dirk van Duijvenbode were other seeds to be knocked out in Saturday's evening session as they all lost in a deciding leg, with Gabriel Clemens, Madars Razma and Jeffrey de Zwaan capitalising to progress.
In contrast to his fellow seeded players, Dimitri van den Bergh put on a dazzling show once again. Fresh from his successive World Series of Darts victories in Copenhagen and Amsterdam, he's chasing a maiden European Tour title, and finds himself in the third round after a 6-2 win over home favourite Florian Hempel.
The Belgian averaged 110.83 during his victory over the German star, and opened with a 152 checkout before landing eight 180s and a ten-darter to set up a third round clash with World Cup winner Damon Heta on Sunday.
Martin Lukeman, a European Tour finalist earlier this year, overcame Ryan Searle 6-4, while Wesley Plaisier knocked out Jose de Sousa for the loss of just one leg and Luke Woodhouse overcame Polish number one Krzysztof Ratajski 6-3.
Rob Cross survived four missed match darts from James Wilson before taking out 104 in the deciding leg of their tie, while Stephen Bunting took out 110 to deny Polish youngster Sebastian Bialecki in another 11-leg thriller.
The £140,000 tournament concludes on Sunday, with the afternoon session's third round followed in the decisive evening session by the quarter-finals, semi-finals and final.
