SAN ANTONIO--Justin DeLoach scored his biggest victory to date, besting Junior Castillo over eight rounds Saturday evening at Scottish Rite Auditorium in San Antonio, Texas.

Scores were 78-72 (twice) and 79-71 for DeLoach, who twice dropped Castillo in handing the Dominican southpaw his first career defeat.

TV UNDERCARD

Brandon Figueroa was given 12 minutes to dispatch Oldier Landon before the NBCSN telecast went off-air. He only needed just over four minutes of ring time, unloading on his foe en route to a savage 2nd round stoppage in the televised walk-out bout. 

A non-stop barrage of punches had Landon pinned on the ropes and in serious trouble for the majoirty of the opening round. Much of the same followed in round two, with Figueroa finally chopping down his foe and depositing him in a corner. No count was necessary as the referee halted the contest early in round two, the end result of a 169-punch blitz from Figueroa as older brother and former lightweight champ Omar stood ringside in admiration.

Ryan Karl remained unbeaten, the latest win coming in an entertaining eight-round unanimous decision over Luis Solis in the NBC Sports Network co-feature.

Scores were 80-71, 79-72 and 78-73 in favor of Karl (12-0, 8KOs), who floored Solis in round three but was forced past round five for the first time in his career. 

It wasn't anywhere nearly as easy for the unbeaten Karl as the final scores suggested, but then such is never the case in any of his fights. True to form, the crowd favorite ate a few right hands in a competitive opening round before settling down and listening to his corner, which now includes Houston-based trainer Ronnie Shields.

Karl's power game prevailed in round three, flooring Solis but unable to put away the bigger foe. It was at that moment he sensed that a distance fight was in store. 

"The size difference was a bit difficult at times," Karl told BoxingScene.com after the fight. The remark is in reference to Solis having missed the contracted weight by more than four pounds on Friday, with the fight only permitted to proceed as planned when the slugger from Mexico came within the ordered 153-pound limit during Saturday's same-day weigh-in. 

It was only part of the confusion surrounding the bout. 

With the modified weight demands also came the belief from Team Solis that the fight was shortened from eight rounds to six. It wouldn't have mattered on the final cards, but it disrupted what Solis thought was a strong finish after rocking Karl with a right hand in round five and fighting on very competitive terms in the sixth heat.

As the bell sounded to begin round seven, Karl approached center ring, while Solis was still on his corner stool, unsure of what was happening. Referee Rafael Ramos called time to order the cornermen out of the ring before allowing the action to continue. 

Ringside fury preceded the eighth and final round. Solis' corner saw fit to pick a fight with TGB Promotions' Britanny Goossen, screaming at the event's co-promoter over the length of the bout and threatening to sue everyone involved. 

Meanwhile, Solis was given no corner instruction heading into the closing three minutes, allowing Karl to coast to the finish line and remain unbeaten.

Darwin Price outboxed Semajay Thomas over eight rounds in their televised opener.

Scores were 80-71 (twice) and 79-72 in favor of Price (10-0, 5KOs), who scored an opening round knockdown and used constant lateral movement to keep Thomas (7-1) at bay. 

The contrasting styles made for awkward moments but turned out to be an academic fight for the judges to score. Thomas sought to be the aggressor but - in direct reference to his opponent's nickname - "Paid the Price" for his courage. An exchange at center ring saw Price duck a left hook and counter with an overhand right to send Thomas to the canvas for the first time in his career. 

Despite the knockdown, Price knew better than to gun for the knockout. Instead, he took heed to the advice given by head trainer Ronnie Shields, imploring his charge to stay outside of Thomas' power and bullrushing. 

By mid-fight. Thomas was bleeding from the nose as well as from a cut under his left eye. Neither turned out to be a factor thanks to the expert work put in by noted cutman Todd Harlib. However, his middle rounds surge didn't make an impression on the judges, who favored Price's cleaner boxing over the course of the evening. 

NON-TV UNDERCARD 

Justin Pauldo registered his second consecutive victory with a six-round unanimous decision over Phoenix-based lightweight Jesus Aguinaga (4-4-1).

Scores were 60-54, 59-55 and 58-56 in a relatively pedestrian affair, but one where Pauldo (7-1, 4KOs) put in rounds. He was also able to absorb the corner instructions from trainer Ronnie Shields, thus justifying his leaving behind his Orlando, Florida home to train out of Houston. 

The win was the second in a row for the 21-year young Pauldo following the lone loss of his career, a split decision defeat to Efrain Cruz in Tampa last July. 

On a night where the "B-side" (red corner) racks up upsets, the biggest came in the form of the first career win for Daniel Arriaga. The San Antonio-bred featherweight hit the jackpot in scoring a one-punch 1st round knockout of Austin's Brandin Chalker, who was unbeaten going in to the scheduled four-round prelim.

Chalker (3-1, 1KO) appeared to be on his way to a fourth straight win to start his career until getting clipped with a single right hand shot just before the bell. The 28-year old fell flat on his back, out before he hit the canvas as the referee waved off the fight without issuing a count.

The official time was 2:59 of round one. Arriaga now moves to 1-2-2 (1KO). 

San Antonio's Kendro Castaneda preserved his unbeaten record with a four-round decision over upside down journeyman Anthony Bowman (10-60-2, 2KOs), Scores were 40-35 across the board for the 22-year old Castaneda (10-0, 3KOs), who floored the 43-year old Bowman in round two but settled for dishing out a boxing lesson as the Jackson, Tenn. native went into survival mode in racking up his 18th consecutive defeat dating back to 2012.

Rynell Riley would normally have Texas-sized support in his home state. However, the Ft. Worth native wound up disappointing the local crowd in scoring a 2nd round knockout of San Antonio's own Tommy Kamara in a battle of middleweight debutants.

The fight nearly ended late in round one when  Riley, 163.75 lbs, connected with a right hand shot that rocked Kamara, 162.5 lbs., who was able to make it to the bell, but wasn't as fortunate in round two. Riley (1-0, 1KO) floored the local middleweight midway through the round, with an ensuing flurry forcing the referee to intervene and stop the fight with Kamara on his feet but unresponsive.
