Luis Concepcion defends his secondary super flyweight title versus old rival Hernan 'Tyson' Marquez, with their third fight coming later Thursday evening at Arena Roberto Duran in Panama City, Panama.
Also on the show, former three-division champ "Sugar" Shane Mosley continues his comeback as he faces Patrick Lopez in a scheduled 10-round super welterweight bout.
Headlining the undercard lead-in bouts, Jezreel Corrales claimed an interim title with a corner stoppage of Mexico's Juan Antonio Rodriguez. The bout was stopped after 11 one-sided rounds, with Rodriguez' corner informing the referee prior to the start of the 12th and final round that their guy was done for the night.
Corrales - whose lone career loss came in his second pro fight - was in control from the outset, with the visiting Rodriguez relegated to the role of opponent in their vacant 130 lb. interim title fight. To his credit, Rodriguez showed a lot of heart, but was just unable to get his punches off in trying to keep up with the house favorite.
As the bout seemed destined to hear the final bell, Rodriguez' corner made the command decision to keep the 27-year old southpaw on his stool prior to the final round.
With an interim title made available, Corrales (19-1, 7KOs) is now paraded around as the 30th world champion to come out of Panama. In reality, he is third line to fellow World Boxing Association (WBA) titlists Javier Fortuna and Takashi Uchiyama.
A feather in his cap comes in that he was able to force Rodriguez to wilt, something that can't be claimed by Fortuna or Billy Dib, both of whom were forced to settle for decision wins. Rodriguez (28-6, 25KOs) also owns a Jan. '14 win over Yenifel Vicente, who recently resurfaced with a highlight reel knockout of Juan Dominguez earlier this month.
Corrales could potentially parlay his interim title into a crack at Fortuna at some point in 2016, or could stay at home and make decent coin as the sanctioning body's third titlist.
Jaime Arboleda earned his way to the Knockout of the Year sweepstakes, delivering a sensational, one-punch 3rd round knockout of Sandro Hernandez in a matchup of super featherweight prospects.
The bout was a punch-per-second for as long as it lasted, though Hernandez throwing hands merely to keep pace. The visiting boxer from Venezuela had more experience in terms of number of fight, but quickly found himself in over his head - before eventually landing flat on his back.
A corker of a left hook from Arboleda (7-0, 5KOs) put Hernandez down and out - and do we mean OUT! - at 1:46 of round three. Hernandez (11-2-2, 6KOs) was kept on the canvas for several minutes as he was immediately attended to by ringside physicians, but left the ring on his feet and with minimal assistance.
Bryan De Gracia maintaned his unbeaten record with a unanimous decision win over Alejandro Palmero over nine rounds of spirited action. Scores of 90-81 (twice) and 90-82 were accurate but competitive within each round. Palmero (7-3, 3KOs) offered a credible account of himself in his first career fight outside of Mexico. De Gracias (17-0-1, 13KOs) came in having scored knockouts in each of his past five starts dating back to last October, but still closes out 2015 on a high note with five wins on the year.
Sayda Mosquera ended a two-fight losing streak in emphatic fashion, blitzing Colombia's Neisi Torres en route to a 1st round stoppage in their super bantamweight clash. A flurry of power punches had Torres (13-4-1, 9KOs) trapped in a corner, prompting a referee stoppage at just 1:03 of round one. Mosquera (8-2-1, 6KOs) picks up her first win since last June, having suffered title fight losses on the road versus Jackie Nava and Mayerlin Rivas.
Angel Rodriguez enjoyed a successful road trip to Panama City, outpointing local super featherweight Eric Castro over nine slow-paced rounds. Scores were 89-82 (twice) and 88-83 in favor of Rodriguez (13-1, 7KOs), who fought for just the second time outside of his native Mexico, each coming in his past two fights. Castro (12-7-2, 10KOs) snaps a four-fight win streak, all of which have come in an active 2015 campaign.
All bouts aired live on TV Max 9 in Panama and also streamed live on the network's website.
