LOUDON, N.H. -- Kyle Busch learned some hard lessons last year as a rookie in the Nextel Cup series. He put some of that knowledge to good use Sunday at New Hampshire International Speedway on the way to his first victory of the season.

A year ago, Busch was the best rookie in NASCAR's top stock car series and had two victories, but the driver who is now 21 years old wound up a disappointing 20th in the season points and had as many bad results as good ones.

"Last year, we made the mistake of worrying too much about what other teams were doing," Busch said. "We kind of lost touch with what we were needing to do. Now we don't worry about anybody else during the race. We just worry about our own racecar."

That was evident Sunday as Busch drove hard and avoided the problems that brought out 11 caution flags and caused trouble for several of the top contenders.  More
