SAN ANTONIO, Tex.—On a show loaded with boxers looking to emerge from the shadows of their more famous family members, Alan Castaño perhaps had the toughest task of the night.

The unbeaten Argentine prospect ultimately prevailed in an eight-round win over Aaron Garcia in their Premier Boxing Champions (PBC) on NBC Sports Network-televised battle, which took place Saturday evening at Scottish Rite Theatre in San Antonio, Texas. However, there was the sense that anything short of a knockout wasn't going to live up to the performance turned in by his older brother Brian, who pitched a virtual shutout over Garcia last December.

Interestingly, the only one who wasn't at all concerned with living up to such expectations...was Saturday's victor himself.

"He was tough but we knew that going in," Castaño (9-0, 5KO) told BoxingScene.com after the fight. "I didn't pay a lot of attention to his fight with Brian. I couldn't tell you if he was any different tonight than when he fought that night. I just know what I wanted to do. He gave me a good test that I needed at this point in my career."

The bout came on a night where Fabian Maidana and Brandon Figueroa took separate next steps in establishing their own respective brands rather than be known as the younger brother of former world champions, with Marcos Maidana and Omar Figueroa, respectively. Both sat in attendance and watched their kid brothers register stoppage wins as they continue to develop as prospects, still a long way from reaching contender status.

Castaño is on the same relative stage as Brian, as both are prospects who are now being featured on the PBC circuit. For the 24-year old super welterweight, the only concern at this point in his career was doing something had hadn't previously done as a pro.

In the end, he was pleased with the returns, regardless of whatever may come of the night.

"I'm very happy with my performance," Castaño insisted afterward. "It was my first time going eight rounds, I had a lot of energy throughout the fight and was able to do everything I wanted in there. Like I said, Brian fought his fight. I have mine. There's no sibling rivalry between us and my goal was to win, not try to outdo my brother."
