FONTANA, Calif. (AP) -- Tony Stewart got his second NASCAR victory of the season Sunday when rain shortened the race at Auto Club Speedway to 129 laps.
The defending Sprint Cup champion has won seven of the last 15 races in a remarkable stretch of dominance, including Las Vegas last month.
Stewart passed Kyle Busch on the 85th lap, and he led when the looming rain clouds finally halted a race run entirely on green flags to that point. The race was called off after a short delay, giving Stewart his 46th career win and his second at Fontana.
Busch finished second, and Dale Earnhardt Jr. added to his strong start to the season in third.
Defending champion Kevin Harvick was fourth, and Carl Edwards was fifth.
