PHILADELPHIA – Junior welterweight Kadeen Hunter stopped Bernardo Manzano in the off-TV portion of Saturday's ProBox TV card in Philadelphia, which featured four quick, brutal knockouts.

Hunter, an 18-year-old from nearby Upper Darby, Pennsylvania, inflicted a punishing second-round stoppage on Mexico's Bernardo Manzano to move to 4-0 (4 KOs). A violent first round featured lightning-quick exchanges, vicious body punching and Manzano touching the canvas at 2300 Arena.

A clash of heads opened up a leaking cut on Manzano, 2-9 (0 KOs), eventually drowning his right eye in blood. He tried to rough up Hunter in the second round and somehow stayed upright in the face of body shots that sounded like a slab of meat thwacking onto a marble counter. But with half his face covered in blood, he motioned to the referee that he was finished, and the bout halted at 2 minutes, 5 seconds of the second round.

Philadelphia's Christian Ortiz, 4-0 (4 KOs), bullied Nicaragua's Haminton Blandon to the canvas three times and stopped him in the second round. Blandon, 3-0-1, 1 KO), was slick and quick, and caught Ortiz with several clean right-hand counters, but Ortiz dwarfed him in the ring and did far more damage with his punches.

After a competitive first round, Ortiz floored Blandon with a left in the second, then scored a second knockdown with a combination. A shot behind the head registered as another knockdown but shouldn’t have, and referee Harvey Dock pulled the plug on the bout at 2 minutes, 49 seconds of the round, with Blandon still punching back but taking immense damage.

Deatwon Young, of York, Pennsylvania, impressed in his pro debut with a first-round stoppage of Mexico's Obed Sepulveda. The aggressor from the start, Young quickly forced Sepulveda back with powerful flurries. He left himself open at times and caught a couple sparse counters on the chin, but he never lost control of the action.

A brutal right hand sent Sepulveda sprawling to the canvas, drool dripping from his mouth, and though he made it to his feet the stoppage wasn’t long in coming. Sepulveda is winless at 0-6-1.

In the opener, Kazakhstan's sharp-punching Bek Nurmaganbet pulverized Costa Rica's Encarnacion Diaz in the first round. Nurmaganbet visibly shook Diaz with the first punch he threw, a right hand that left Diaz blinking uncertainly, as if trying to clear his vision.

Nurmaganbet’s punches landed with fierce thuds, making the entire canvas shudder, as well as Diaz’s body. A clubbing blow behind the head sent Diaz to a knee. He rose only to be sent down by a series of cleaner punches – but with Diaz clearly down, Nurmaganbet struck him with a hard right hand for which the referee did not penalize him.

Diaz, 20-6 (11 KOs), did not beat the count, and Nurmaganbet moved to 14-0 (12 KOs).
