Arnulfo Castillo: Super Featherweight Champion

Arnulfo “Chico” Castillo is a Mexican former professional boxer from Chihuahua who competed at super featherweight. He built a strong regional career and challenged for the WBO world title three times, but did not win a world championship. A retrospective by Diario.mx describes his title attempts and later work as a boxing trainer.

World title challenges

Castillo’s best-known run came at junior lightweight. He challenged WBO super-featherweight champion Anatoly Alexandrov in January 1999 and lost by eighth-round technical knockout. BoxRec’s record and the contemporary career retrospective identify him as a serious contender who came close across several world-title opportunities. The result is recorded in BoxerList’s bout history.

Castillo’s profile illustrates the distinction between an accomplished title challenger and a world champion: he competed for major honors but never captured the WBO belt. After his professional career, he remained involved in boxing as a trainer in Chihuahua. His story is best remembered locally for persistence at the highest level and for the work he continued to do in the sport.

Career Milestones

Castillo’s title challenges should be distinguished from the championship achievements of Alexandrov and the other titleholders he faced. The title challenge ended in a stoppage defeat, leaving Alexandrov as champion. His later training work belongs to another stage of his involvement in Chihuahua boxing. The nickname “Chico” identifies the same competitor across those records, rather than a second boxer with a separate career. That continuity connects the experienced regional fighter, the world-title challenger and the trainer described in the local retrospective.
