Scott (Pitbull) Clark has displayed dogged determination after sinking his teeth into the sport of kickboxing relatively late in life.
Clark was 20 when he first stepped on the mat and, seven years later, finds himself headlining his first fight card tonight.
The Pitbull will take on Switzerland's Nenad Grujic for the IKF World Light Heavyweght Muay Thai belt when the Calgary Amateur Kickboxing and Muay Thai Association presents Reserve Judgment at the Sarcee Seven Chiefs Sportsplex.
"Seven years has really gone by fast," said the 5-ft. 10-in., 175-lb. Clark, who owns an amateur record of 21-3-1. "But what you put in, you get out. I have gone fairly hard at this and not missed much time out of the gym."
Content with more mainstream sports such as baseball and hockey as a youngster, Clark always had an interest in kickboxing and decided to give it a try as an adult.
"Getting into it, I realized right away it was for me," recalled Clark. "I realized the harder I pushed myself, the further I could go."
It soon became both a passion and lifestyle, as Clark now teaches the sport for a living under local kickboxing guru and three-time professional world champion Mike Miles.
Clark doesn't know much about Grujic -- not even his age -- although he has tried putting his amateur sleuthing skills to work.
"If tape is available, sure you want to watch it to see what type of fighter your opponent is," said Clark. "But that's not always possible. In regards to this guy, I don't know anything about him. I've tried to research him a little bit on the Internet and I haven't found anything about him."
Given how many times Miles' crew has been featured on TSN, finding footage of Clark isn't tough.
"Where there's a plus, there's a minus," said Clark. "We've had a lot of international exposure and, in general, we've done well here so that gives them a chance to see me."
