American boxer Robby Gonzales endured a chorus of boos to book his spot in the under-80 kilogram final after beating home favourite Vladimir Mironchikov in the semi-finals of the International Boxing Association (AIBA) Men's World Boxing Championships in Belgrade.

In the most heated bout of the night at the Štark Arena, Gonzales came from behind to defeat the Serbian by a 3-2 split decision, ending a match full of fantastic flying punches and offensive tactics.

He takes on Belarus boxer Aliaksei Alfiorau, who claimed a 4-1 split victory over the Russian Boxing Federation's (RBF) Savelii Sadoma.

Temirtas Zhussupov gave Kazakhstan its first finalist by winning the opening bout in the under-48kg category by unanimous decision against Belarus' Yauheni Karmilchyk.

Another 5-0 victory followed for Wuttichai Yurachai of the Thailand Boxing Federation (TBF), who was a clear victor against Georgia's Sakhil Alakhverdovi.

A second Kazakh made a final shortly after, when under-54kg fighter Makhmud Sabyrkhan was the unanimous winner against Akash Kumar, who finished as India's only medallist.

Kumar's mother died just before the National Championships and he has used her passing as inspiration at the tournament.

Lasha Guruli of Georgia had to forfeit his under-67kg bout too, giving the United States' Omari Jones a bye to the final, where he will face Sewon Okazawa of Japan, whose agile tactics were largely nullified against Kazakhstan's Ablaikhan Zhussupov but still eked out a 4-1 win.

A second Azeri finalist would not be realised as Davit Chaloyan of Armenia defeated regional rival Mahammad Abdullayev unanimously.

Chaloyan takes on the RBF's Mark Petrovskii in the over-92kg final, who survived a late knock down by Trinidad and Tobago's Nigel Paul to take a 4-1 victory.
