Niamh Fay is the new European Youth champion after another high-octane, high-punching performance in Sofia, Bulgaria.

The Swords BC bantam beat Croatia's Nikolina Cacic on a 4-1 split decision – 30-27, 29-28, 29-28, 29-28, 28-29 – to take the 54kg title.

Fay dominated the first two rounds and rocked her opponent with big hooks off both hands en route to victory.

Cacic, to her credit, stood up to Fay’s relentless aggression and won the last frame 4-1, but the Dubliner had more than enough in the bank to take the gold medal after winning the first and seconds rounds 4-1 and 5-0.

Fay won four fights en route to gold in Bulgaria.

Ireland will be taking home one gold and three bronze medals from Sofia, courtesy of Fay, Daina Moorehouse, Leah Gallen and Lisa O’Rourke.

Meanwhile, at the men's senior World Championships in Ekaterinburg, Russia, Irish heavyweight Kirill Afanasev defeated Australian Austin Aokuso on a unanimous decision.

The Smithfield BC fighter moves on to Sunday's last 32 stage, where he will face Radoslav Pantaleev of Bulgaria.

Light-heavyweight Kane Tucker had earlier lost a unanimous call to Kyrgyzstan's Erkin Adylbek.
