FORT WORTH, Texas — The NASCAR Sprint Cup Series race at Texas Motor Speedway was postponed Sunday because of rain. It was to be run Monday. Tony Stewart took the pole in qualifying Saturday, with Brad Keselowski starting second and Kevin Harvick third. It’s the third NASCAR race out of seven this season to be hampered by rain. The season-opening Daytona 500 was stopped for more than six hours, and the race at Bristol Motor Speedway had two delays totaling more than five hours. NASCAR’s new track drying system requires two hours to dry the 1.5-mile speedway, but the unseasonably cool temperatures at Texas Motor Speedway made the task more difficult. — AP
