"Rafael Romero doubled his record to 2-0 beating the flamboyant Edmontonian Jason 'The Troll' Adams in a four round unanimous decision".

So he decided to call it quits and to stick to racing. The new sponsors are more then enough to keep Adam's extravagant life style at the level he is accustomed to.
