DETROIT -- Graham Rahal won the first of two Detroit Grand Prix races, easily holding off Scott Dixon on Saturday.
Rahal won the pole earlier in the day with his Honda-powered car and became the seventh IndyCar driver to win the first seven races of the year. He raced to his fifth career victory and fourth in two-plus years for Rahal Letterman Lanigan Racing.
Rahal made a last-lap pass of James Hinchcliffe for his previous win last year, when he beat Hinchcliffe by eight-thousandths of a second in the closest finish for an IndyCar race at Texas.
