WASHINGTON, D.C. – Making his pro debut Friday here at the Entertainment & Sports Arena, junior bantamweight Jordan Roach – Lamont Roach Jr.’s younger brother – clearly outclassed veteran opponent Luis Domingo Hernandez Cambero, scoring two knockdowns en route to a shutout unanimous decision.

The first round of Roach's first pro fight started as well as it could have, barring a knockdown or knockout. He dominated all three minutes, starting off by landing two left hooks, then two more. Cambero came forward and Roach pushed him back with – what else? – a left hook. Soon came a three-punch combination and a four-shot combo. A few shots landed while Cambero was on the ropes, and Roach wobbled Cambero just before the bell.

The knockdowns would come soon enough. Roach scored the first of them in the final minute of the second round. Cambero rose and complained that he was hit behind the head. 

Cambero came forward to start Round 3, and Roach dealt capably with his opponent's awkward aggression, dodging many of Cambero’s shots and lacing in his own. A thudding left hook to the body from Roach left Cambero no recourse but to acknowledge the blow. Soon Cambero was on unsteady legs, attempting to hold while Roach continued to score. Roach remained patient, landing two shots that put Cambero down again as the round came to a close. 

Roach wasn’t able to finish Cambero in the fourth but otherwise coasted to victory. Two judges had it 40-34, while the third saw it 40-35.

Roach, of Upper Marlboro, Maryland, is now 1-0 (0 KOs). Cambero, of Santiago de los Caballeros in the Dominican Republic, is now 15-14-1 (10 KOs).

In a welterweight fight, Greg Outlaw stopped Isidro Curiel in the fourth round of a one-sided match.

Outlaw, a 30-year-old southpaw from Bowie, Maryland, scored with a good left cross and right hook in the second. Later in the round, Outlaw let loose with an extended combination that had Curiel reeling and attempting to tie up.

Outlaw continued to dominate in the third round, especially with his left hand. He sent it to the body and followed with a right hook to the head. He countered with a left, then promptly led with another. And a left cross sent Curiel staggering backward into the ropes.

Outlaw worked more from his back foot in the fourth round, seeking to draw Curiel in and catch him with a counter. The tactic worked: Outlaw walked Curiel into a right hook and followed up with a left hand. When Curiel went idle, Outlaw took advantage and attacked, landing a shot that sent Curiel to the ropes. Outlaw let loose with a lengthy flurry until the referee jumped in. The end came two minutes and 38 seconds into the round.

Outlaw moved to 15-2 (9 KOs), picking up his third straight win since getting knocked out in two rounds last year by Juan Meza Angulo. Curiel, a 33-year-old from Ciudad Madero, fell to 11-4-1 (6 KOs).

Unbeaten lightweight Deric “Scooter” Davis made quick work of his opponent, scoring a second-round technical knockout over Matias Agustin Arriagada.

The first round was target practice for Davis, who would throw a hook to the body and follow up with one to the head, and then he’d throw the same combination in reverse. Arriagada ultimately needed some relief, taking a knee after one body shot and rising at the count of eight.

Early in Round 2, Arriagada attempted a left hook and ate a right hand counter in return. Davis soon forced Arriagada to a neutral corner and unleashed a combination that put Arriagada down again. Once more, Arriagada rose, though he wouldn't remain on his feet for long. Davis promptly dropped him again, and the referee waved the action off. The end came one minute and 15 seconds into the round.

Davis, a 21-year-old living in Fort Washington, Maryland, is now 4-0 (4 KOs). Arriagada, who hails from Buenos Aires, is now 6-12 (3 KOs).

Travon “The Sniper” Marshall, a prospect competing between welterweight and junior middleweight, won a unanimous decision over Luis Midyael Sanchez.

The first round was fought almost exclusively at close quarters, with Marshall and Sanchez focused on exchanging body shots. Toward the round’s end, Marshall, a 23-year-old from the neighboring town of Capitol Heights, Maryland, began to add occasional follow-ups upstairs.

The second round began more at mid-range, giving the fighters' midsections a brief break before they returned to their phone booth. One fighter would throw and land two, then the other would take his turn. Sanchez appeared to be doing the better work, and then Marshall replied with an uppercut and a pair of hooks. Given Sanchez's come-forward approach, Marshall found another opportunity to walk his opponent into a right uppercut as the round came to a close.

Marshall tried to maintain some distance in the third, boxing on his back foot and looking for opportunities to catch Sanchez as he moved forward. In the fourth, Marshall scored with a crisp left-right combination that may have been his best punches of the night so far. Although Sanchez took it fine at the moment and soon retaliated, the action seemed finally to be slowing down the 30-year-old from San Juan, Puerto Rico.

Sanchez continued to come forward in the fifth, albeit with less steam behind his punches. He still was the more active fighter, while Marshall sought opportunities to load up. And in the sixth and final round, Sanchez tried to finish as he began, on the inside and targeting the body. Marshall obliged, further sapping the energy of his tired opponent, and he landed some blows that put Sanchez in survival mode for the remainder of the fight. Marshall attempted to put Sanchez away but had to settle for the well-earned decision win.

The final scores: 60-54 (twice) and 59-55. Marshall improved to 10-1 (8 KOs) and has now won two straight since suffering a second-round TKO loss to Gabriel Maestre last year. Sanchez fell to 9-6 (6 KOs) and has now dropped five in a row.

In the show’s opener, junior welterweight Eric “El Toro” Hernandez won a unanimous decision over Jonatan Hernan Godoy.

Hernandez came forward from the opening bell, spurred on by a vocal contingent of fans who arrived early to support the 30-year-old from nearby Ashburn, Virginia. He attacked with flashy flurries, forced Godoy to the ropes early on, and did a good job of ducking Godoy’s sporadic left hooks. Later in the round, Godoy was the one moving forward, landing a pair of body shots and trading hooks. Hernandez’s blows remained superior in quantity and quality, however.

In the second round, Godoy absorbed some early punishment but dug in and fought back. The 32-year-old from Buenos Aires was slower and outmatched but nonetheless determined not to have come all this way just to go away easy. Hernandez responded with an extended combination and promptly resumed control.

Hernandez earned the crowd's approval in the third round with a right uppercut followed by a left hook. Godoy continued to press forward, recognizing that his time was limited in this four-rounder.

In the fourth and final round, Godoy controlled the early action, pushing forward and landing flush with two- and three-punch combinations. Hernandez was able to lace in a five-punch combination later, including a nice left uppercut that popped Godoy's head. And Hernandez was the one landing better as the fight came to a close.

The final scores were a shutout, even if the rounds were otherwise competitive. All three judges saw Hernandez ahead, 40-36. Hernandez moved to 11-1 (5 KOs) while Godoy is now 7-19 (1 KO).
