Sousa, currently 176th in the world rankings, defeated Ritschard, 297th in the world hierarchy, and coming from qualifying, 6-3, 6-2, in one hour and 10 minutes.
In the fight for access to the semi-finals, Guimarães will face Dutchman Tim Van Rijthoven, 265th in the ATP ranking, in what will be the first meeting between them.
