The Dublin light flyweight took on German Ibrahim Salah in the Round of 32 in Russia and claimed a unanimous decision victory to make it four out of four for Ireland so far.
Moore began well on the back foot in a cagey opener which saw both told by the referee to engage more, Moore perhaps landed the cleaner shots once they began to trade in the final minute, in which the pair wrestled to the ground twice.
A clinch-filled second again saw the better work come from the Irishman, and there was a sense that a bit of needle developing between the pair in a what was becoming a scrappy, physical, fight
Salah began well in the third as he went on the attack, but Moore finished very strongly and staggered the German toward the conclusion to seal the win.
Moore was handed the victory on a unanimous decision and now faces a Last 16 bout against Filipino Carlo Paalam on Monday morning.
