Brad Keselowski won the NASCAR Nationwide Series event at Charlotte Motor Speedway on Saturday, leading the final 67 laps to give Penske Racing a winning start on auto racing's biggest weekend. Keselowski raced to his first Nationwide victory of the year. He'll try to double up in Sprint Cup's longest race of the season, the Coca-Cola 600 on Sunday night. In between comes the Indy 500, a race that owner Roger Penske's cars have won 15 times. Penske driver Ryan Briscoe will start from the pole there Sunday.
