They beat French duo Bastian Kersaudy and Lea Palermo on Thursday evening
Chloe and Sam Magee are just one win away from a medal at the European Championships.
The Donegal siblings earned a place in the quarter finals with victory over the French pair of Bastian Kersaudy and Lea Palermo.
The victory comes after their result on Tuesday, when they overcame Dutch duo, Jacco Piek and Selena Arends.
A win in the quarter finals guarantees at least a bronze. They will now face either Finland or Poland in the next round.
