Asian silver-winner Deepak Kumar (52kg) on Friday stunned Olympic and world champion Shakhobiddin Zoirov of Uzbekistan to storm into the finals of the 72nd Strandja Memorial Boxing Tournament in Sofia, Bulgaria.
Deepak clinched one of the most memorable wins of his career with a 4-1 win over more fancied Zoirov, who had claimed the 2019 world championship title beating India's Amit Panghal.
Zoirov is also a silver-medallist from the Asian Games and the championships.
In the quarterfinals on Thursday, Deepak defeated Bulgaria's Darislav Vasilev 5-0.
