Umm no.. Kenny Rogers threw a perfect game as well with the Rangers. It's a stroke of luck and decent skill at best.
He is a good enough pitcher though.
Yeah, that's true Kenny did, but Buehrle is one of only 6 to throw a perfecto and a no hitter. It was a masterpiece really. Like Ozzie said, he usually pitches to contact but yesterday the change and curve were sitting people down left and right and that makes it even better, he was definitely on top of his game.
