“I had heard about (American Top Team) and seen them on TV a lot. I liked the fact that they were winning consistently and I wanted to train where the best people were training.”

Zevallos’ opponent, Walker, is a Denver native and former student of Sabaki Karate under martial arts legend, Clarence Thatch. In the late ‘90s, Walker utilized his striking skills to go on an unbeaten, 5-0 run in “Toughman” competition.

“The Sabaki helps my stand-up (skills) in MMA a lot,” explained Walker. “I’m able to swing my opponent and knock him off balance. It’s a matter of using his weight against him.”

Walker made his greatest impression in the fight world to date on August 11, 2001 when he stopped Carter Williams in the second round of their K-1 matchup at Las Vegas’ Bellagio Hotel and Casino. Williams went on to capture the K-1 North America tournament championship two years later.

In the main event, knockout artist and Denver native, Duane “Bang” Ludwig (16-8), will attempt to avenge a previous knockout at the hands of “The Ultimate Fighter” season three veteran, Sam “The Squeeze” Morgan (19-10).
