Masters champion Joe Cullen was unable to repeat the form of Thursday's Premier League triumph in London as he lost out 6-3 to Rowby-John Rodriguez.
Rodriguez now faces Daryl Gurney after the former World Grand Prix winner came from 4-3 down to defeat Eddie Lovely 6-4, sealing victory with a 120 checkout.
Ryan Searle finished six doubles from ten attempts in his 6-2 win over Adam Gawlas, checking out 143 and 114 in the process, and now plays Damon Heta after the Australian edged out Mickey Mansell in the deciding leg of a high-quality affair.
Krzysztof Ratajski produced a flawless display of finishing with six doubles from as many attempts in defeating Kim Huybrechts 6-2.
He now plays reigning European Champion Rob Cross, who was a 6-5 winner against Jelle Klaasen as a 14-darter snatched victory in their deciding leg.
