The Cavan flyweight stopped Hungary’s Krisztina Beri in the second round to progress to the last 16 in the 51kg class.
Smith, who used her backhand to solid effect in the first, dropped the brave Magyar with a left hook in the second and her opponent took another count from another left moments after visiting the canvas.
The ref then waved it off after Beri took a third count from a righ near the end of the frame.
Smith will be back between the ropes tomorrow with a Titanic task in Turkey’s Naz Buse Cakiroglu.
The Istanbul-based southpaw, who receive a bye into the last 16, claimed gold at the European Games in Minsk earlier this summer and is the No. 1 seed in Spain.
