John Joe Nevin has moved to number one bantamweight in the updated world rankings published by the International Amateur Boxing Association.
The London 2012 silver medallist picked up 800 rankings points by virtue of winning gold at the European Championships in Belarus last month.
Those points sees the Cavan BC bantamweight leapfrog Cuba’s Jorge Alvarez-Estrada - who he beat in the 2012 Olympic semi-final - into pole position.
Nevin’s elevation means that Ireland now has two boxers ranked No 1 in the world for the first time as Katie Taylor has occupied the women's lightweight top spot for the last seven years.
The Bray woman, the current Olympic, world, European, EU and Irish champion, will go into 2014 as World number one for an eighth consecutive year as there are no ranking tournaments for women in 2013.
Paddy Barnes, who won silver in Belarus, has moved up the light flyweight rankings to third - equal on points with Thailand’s Kaeo Pongprayoo, who is in second spot.
Michael Conlan, also a silver medallist in Belarus, remains third in the flyweight rankings, while Jason Quigley, a gold medallist in Belarus, is included in the world rankings for the first time. Quigley comes in joint seventh spot with Uzbek Shurat Abdullaev in the middleweight division.
World No 1 Ievegen Hyytrov of the Ukraine, Romania’s Bogdan Jurantoni and Germany’s Stefan Haertel – all of whom Quigley beat in Belarus – are ranked higher than the Donegal man.
