Kevin Lisch became a Perth Wildcats superstar by leading the 'Cats to its fifth championship on Friday and his amazing shooting display was the best game of his career.

Lisch can't recall ever winning a championship of any sort at least in the last 10 years and in his first season of professional basketball, likely as far from St Louis as he could get to ply his trade, he will go down as a Wildcat great after his 29-point display in three quarters.

Lisch hit 7-of-13 from the field including 5-of-9 from three-point range and some of those were incredible shots, most notably the banked in three from near half-court just before three quarter-time.

He went on a 13-point tear to finish the third period and secure the Wildcats' victory and championship. It was the biggest stage the 23-year-old has played on and the best game he's ever played, so that made winning the championship even more satisfying.

"I'd have to say yes (his best ever game). It was on the biggest stage and I got some crazy shots to fall there, but it's just an amazing feeling to win a championship," Lisch said.

"It is my first one. I might have got one when I was 10 years old or something, but this is the first one I've got that I remember and it's just an unbelievable feeling to win a championship and being the best team here in Australia."

When Lisch graduated from St Louis University where he played some good basketball with the Billikens, he always thought he might end up playing somewhere as far away as Australia, but he'd never heard of Perth.

Now not only has he heard of it, but he's a household name in the city and his whole family got up to watch him win the championship back home.

"I'd heard of Australia, but never Perth. Once I signed here, I did a lot of looking into it and ever since I got here the people have just been amazing," he said.

"I figured I was going to go pretty far away to play ball anyway, so what's another 10 hours. They watched it on the internet. I think it was about 5.30 in the morning, but they got up to watch it and I'll talk to them soon."

Lisch was told all season long by coaches Rob Beveridge and Mark Radford, and his teammates to take the opposition on both with his shooting and ability to get to the basket. He kept working on that and it paid off massively as he was the Larry Sengstock Medallist as Grand Final MVP.

"I have the team and Bevo constantly chirping in my ears to back myself and having that confidence knowing they are behind me helps things. Then I also work pretty hard myself and it all just came together."

Lisch played under Rick Majerus at Saint Louis, who gave him a glowing reference, and a former Beveridge pupil Chris Harriman gave the newly-appointed Wildcats coach the heads up that Lisch was quite a talent.

Beveridge was quick to pounce to sign him and the move couldn’t have worked out better.

"A mate of mine rang me up who I coached over 10 years ago and he was coaching at St Louis and he said that he has a young guy who is everything that I need. He said he wasn’t a flashy superstar, but he does everything well, he's hard-nosed, can shoot the ball and does everything," Beveridge said.

"That sold me straightaway. I could have got former NBA players and things like that, but I wanted to develop a culture in the club and it wasn’t about winning in the first year. It was about getting a bunch of players together who were going to play hard, train hard and just want to become better. The conditions were if you want to be in the team that's what you had to do."

Certainly Beveridge didn’t think that Lisch could dominate a Grand Final the way he did on Friday, but he's been impressed with him all season and hopes he's around to defend the club's championship.

"I wouldn’t say I thought he could dominate a Grand Final because I never expected to get there, it was all about building some foundations. He was everything I was looking for with a work ethic, the character, the attitude and because he's worked so hard he's become a very good player," he said.

"He is still young and is only going to improve. We want to recruit a young group of players and Kev has earned his right to continue for sure."
