Julio Cesar Martinez is keeping his title…

The 25-year-old Mexican professional boxer, the reigning WBC flyweight world champion, made quick work of Moises Calleros on Friday night on DAZN at the TV Azteca Studios in Mexico City to retain his belt via second-round TKO.

A three-punch salvo that included a left hook sent Calleros to the canvas in Round 1, and while Calleros survived to make the second round, Martinez’s frenetic attack didn’t let up.

Martinez overwhelmed him with a series of power punches, and had Calleros up along the ropes in the second, where Calleros was swarmed by another onslaught before referee Cesar Castanon ultimately stepped in to wave off the fight at 2:42 minutes of the round.

Calleros (33-10-1, 17 KOs) came in as a late replacement and was almost six pounds over the flyweight limit, but the extra weight didn’t help him against Martinez (17-1, 13 KOs).

Calleros simply couldn’t take the swift and powerful punches of Martinez, who is quickly making his case as one of the most entertaining fighters in the sport, thanks to his aggression and punching power compared to his size.
