TOKYO — Albert Batyrgaziev of Russia won the boxing featherweight gold medal on Thursday, and in the process stopped the first of three Americans trying to win gold in men’s boxing for the first time in 17 years.

Batyrgaziev, using flurries of speed and playing squarely into the rules of amateur boxing that reward many punches in a short amount of time, won a 3-2 split decision over Duke Ragan, a fighter from Cincinnati who, like Batyrgaziev, is in the early part of his professional career.
