Argentina's Peralta Jara has won the final heavyweight bout of the afternoon session with a confident display against Algeria's Chouaib Bouloudinats.
The first talking point came when the Algerian was judged to have landed a low blow, giving Jara two points.
The Argentine then took control of the bout with two right hands that landed right on the button.
Jara worked the jab effectively, using his longer reach to keep Bouloudinats out of range and out of trouble to increase his advantage to seven points.
The 21-year-old wrapped up a comfortable 13-5 triumph in the third round.
