This weekend, Gennady Golovkin enters the ring for the sixth time in 17 months when he faces Osumanu Adama in Monte Carlo. The Olympic silver medalist and undefeated WBA middleweight champion from Kazakhstan was among the biggest breakout stars of 2013.
Don't expect him to start slowing down anytime soon.
Several fighters from the former USSR had banner years in 2013. The former Soviet Republics were long known for their outstanding amateur programs.
Now, a generation removed from the fall of the Soviet Union, fighters from Eastern Europe and Central Asia are transforming the face of the sport.
These six stars from 2013 have bright futures ahead of them.
