Filipino masters Efren "Bata" Reyes and Francisco "Django" Bustamante were playing Tom Storm and Nick Van Den Berg, respectively at presstime.
Hsia was a late call up after compatriot Ching-shun Yang turned down the offer of a trip to Holland and he grabbed the opportunity with both hands.
He ran out rack after rack and Bergendorff’s misery was compounded when he missed a straight 9-ball at 7 - 2 down and that gifted the match to the talented Hsia.
That victory earned him a last eight match up against either World Champ Thorsten Hohmann or Holland’s Rico Diks.
In other matches, Finnish Mika Immonen trounced German ace Ralf Souquet, 8-5, to arrange a quarterfinal match with Alex Lely, who booted out Steve Davis, 8-3.
