Tin-Tin Ho won her group at the European Under-21 Championships in Portugal, but Emily Bolton had to withdraw through injury.
Ho won all three matches against opponents from Slovenia, Italy and Hungary to top Group 12 and move into the second stage.
There, she will play in Group G against Xuan Zhang of Spain, Poland’s Julia Slazak and her doubles partner, Karoline Mischek of Austria. The matches all take place on Friday.
Ho & Mischek advanced in the doubles, winning their first-round match 3-0 against Raquel Martins of Portugal & Tatsiana Chakavaya of Belarus. They next face Klara Cakol & Marta Vukelic of Croatia in the last 16 on Saturday.
Bolton had to pull out of both the singles and doubles – where she was due to partner Veronica Mosconi of Italy – because of a tricep injury.
Bolton completed her first match, which went the distance, against Ozge Yilmaz of Turkey, but was unable to continue in the tournament after that 4-3 defeat.
There are no English men competing in Gondomar – Tom Jarvis was unable to travel due to club commitments.
