FONTANA, Calif. (AP) -- Tony Stewart has won his second straight NASCAR Nationwide Series race, holding off Kyle Busch again.

Nine days ago at Daytona, Stewart beat Busch in a 1-2 Toyota sweep in the Nationwide season-opener at Daytona. He made it look a lot easier in the rain-delayed race at Auto Club Speedway today, leading 136 of the 150 laps.

It's Stewart's fourth victory in what was previously known as the Busch Series. But it's his first win at any other track besides Daytona International Speedway.
