Antioch kickboxer Katrina Nahe is only 15, but she can already say she’s conquered the world.

Nahe, a freshman at Deer Valley, defeated Tisha Balentien of Holland on Saturday by unanimous decision at the International Kickboxing Federation World Muay Thai-Kickboxing Championship in Oakland.

The five-round world title bout needed all five rounds to be decided, but once all was said and done, the judges awarded Nahe the victory. “It was an epic battle, to say the least,” said Nahe’s trainer, Dennis Guila. “It was the kind of fight that people were roaring on their feet when it all took place.”

Coming into the fight, Balentien’s record was 27 wins (12 by knockout) and only four losses. Guila gave Balentien plenty of credit as a worthy opponent for Nahe.

However, now that Nahe is on top, she will have to defend her title. Guila said that Nahe’s victory bodes well for the future of the young fighter, who knows it will probably not be her last international title fight.

“As far as her reaching this plateau in her young career, it certainly puts her at a whole new level in what she does as a fighter,” Guila said. “This definitely will be opening up more doors for her on the world market. … This is a very prestigious title, which it’s up to her to keep and defend now.”

This is Nahe’s fourth IKF belt. Last year in Orlando, she defeated her opponent in just 1 minute, 7 seconds.
