Nicola Adams eased past Holland's Abbygail Deekman to guarantee at least a bronze medal at the European Union Championships in Hungary.
The Olympic champion followed up her comeback win over Italy's Terry Gordini on Monday with a one-sided victory over Deekman, who was retired on her stool.
Lisa Whiteside secured a second medal for Great Britain when she outpointed Poland's Karolina Michalczyk in the 54kg quarter-finals.
Ireland's Olympic champion Katie Taylor also reached the semi-finals with a fourth-round stoppage over Hungary's Benke Sara.
Taylor, who is bidding for her fifth consecutive EU title, will next meet Finland's Mira Potkonen on Friday.
