AVONDALE, Ariz. -- Johnny Case hasn't lost in his four UFC bouts and has an MMA winning streak that dates back to 2010, a streak that he can attribute to his training and his focus.

And maybe one other thing helps the fighter who carries the nickname "Hollywood."

"The thought of me getting my ass kicked is a good motivator," Case said. "I just have to stay humble and grounded and realize that there's always places I can get better and there are always guys that are better than me."

Case (22-4) will look to extend his win streak to 13 when he takes on Jake Matthews (10-1) Saturday at UFC Fight Night in Brisbane, Australia. Matthews, an Australian, will have the home crowd behind him for the lightweight match.

The 26-year-old Case is no stranger to that situation. He made his UFC debut in 2014 and beat Japanese boxer Kazuki Tokudome in his home country. In his most recent fight in November, Case won a unanimous decision over Brazilian Yan Cabral in Sao Paulo.

"The atmosphere is going to be pretty hostile being I'm fighting one of their golden boys but I'm used to that," Case said. "I really thrive on the underdog role and I don't mind the hostile crowds one bit.

"I really enjoy it because they're really hostile before the fight. And after I win, they're all applauding and super respectful. To be able to sway the crowd like that is pretty awesome."

Case believes his streak, entering its sixth year, puts pressure on his opponents and in some ways he can expect a strong performance from his opponent just because of his run of victories.

"When I get into a fight, I want that opponent to give me their best," Case said. "I expect it because they're getting the best out of me."

Like many athletes on streaks, Case focuses more on himself than his opponent. He knows what his opponent can do but doesn't spend so much time on his opponent that he doesn't focus on his own strengths -- he has 15 wins by knockout and has won 14 of his matches in the first round.

"I study my opponent before the fight and see the things that he likes to do or things he might be strong at and then that's it," Case said. "And then I focus on things I'm good at and what I'm going to do in the fight. From the first week on [in training], he doesn't cross my mind.

"Anything he does, I can't control anyway. I can only control myself."

Before heading to Australia, Case took in the NASCAR race Sunday at Phoenix International Raceway, a nice diversion to his training. The NASCAR fan base has been heavily exposed to UFC as 2014 Sprint Cup champion Kevin Harvick's sports management company represents Meisha Tate and Donald "Cowboy" Cerrone.

"I definitely feel like the fan base is closer related -- the racing, fighting, drinking down-home kind of guys," Case said.
