After victories over Nikoloz Kakhelashvili of Italy and Maksim Safarian of Russia, Hancock would draw Artur Aleksanyan of Armenia in the semifinals. Aleksanyan won the last four World and Olympic Greco-Roman championships at 98kg and is one of the pound-for-pound best wrestlers in the world in any style. 

Hancock showed no fear, going after Aleksanyan right off the whistle, ensnaring the six-time world and Olympic medalist in a sag-headlock and decking the Armenian giant in under a minute. 

But Hancock wasn't done yet. He came back the next day and beat Nikolay Bayryakov of Bulgaria in the finals, 7-0, to win the Poland Open 97kg Greco-Roman gold. 

Congratulations to G'angelo Hancock (USA) on winning the Ziolkowski at 97 KG. He took out 4x World/Olympic champ Artur Aleksanyan (ARM), 2015 Junior world champ Nikoloz Kakhelashvili (ITA), Maksim Safarian (RUS), and 2017 European bronze medalist Nikolay Bayryakov (BUL)

A tremendous overall performance by Hancock, who showed that America is bringing some serious Greco-Roman firepower to Budapest.
