A year ago at California Speedway, Kyle Busch became the youngest winner in the history of NASCAR's top stock car series. He was 20 years, four months and two days old at the time.

Since then, he has won two more times and Saturday was inducted into the California Speedway Walk of Fame, joining older brother Kurt, inducted two years ago.

``It's pretty cool,'' the younger Busch said. ``It's extra special to be here anyway, but to be a couple spots over from my brother is pretty neat as well.''
