Joe Gibbs Racing's Toyotas haven't lost a Nationwide race on their unofficial home track since 2007. Busch pushed ahead late in a back-and-forth duel with Nationwide points leader Hornish's Ford to win his second straight Nationwide race.
What's more, Parker Kligerman drove his Kyle Busch Motorsports Toyota to a fourth-place finish. Regan Smith was third, and Austin Dillon came in fifth ahead of Kyle Larson.
Through changes in cars and crew chiefs, Busch has won six times at Fontana. He's the Nationwide career victory leader with 54.
