Good Sports: 15-year-old boxing champ Marc Castro

FRESNO, Calif. (KFSN) -- At just 15 years old, Sunnyside High School sophomore Marc Castro is young enough to remember when he was sitting ringside, watching older boxers do things he could only dream of.

"I would not like workout hard. I would just work out and then go to sleep at the gym because my dad has his own gym," Marc said.

Now fighting out of Aleman Boxing Gym in Fresno, it's Castro who now has the attention of the youngsters, thanks in large part to a whirlwind six months that saw him win the U.S. National Boxing Junior Olympics in West Virginia and then the USA Boxing Junior Open National Championships in Reno earlier this month.

"I just felt like any other match that I won. But then like my family was all happy so I'm like I did it. I won something big," Marc said.

"I felt like busting tears right there because it's emotional when you call that USA Team. You made it to a team. It's like wow," said Tony Castro, Marc's father and coach.

Understandably, Tony Castro couldn't be prouder of his son. He said, "Not because he's winning all these championships, but because he's doing well in school. He's a good kid. It made me feel good because his dream came true."

And it's not just because of Marc's potential in the ring. Just after winning in Reno, the first thing he did was hug his mom and sister.

"It was great. They were cheering me on. I could hear them during the fights," Marc said.

"I mean it was a little family but with a big holler for everybody," Tony Castro said.

Now with the win in Reno, Marc will represent his country in international competitions, giving Fresno another boxer ready to take on the world.

"We talked to some coaches. They just said that I just had to work hard again, don't change anything. Because if you change anything, you're going to change the outcome of the fight," Marc said.
