MOTEGI, Japan — New Zealand’s Scott Dixon won the Indy Japan 300 on Saturday to take over the IndyCar series points lead with one race remaining.

Dixon, who started from the pole position and led for most of the race, took over the lead for good on the 164th lap and finished 1.4475 seconds ahead of Target Chip Ganassi teammate Dario Franchitti for his fifth win of the season.

Dixon leads the standings with 570 points followed by Franchitti, who has 565.

Ryan Briscoe, who went into Saturday’s race with a 25-point lead over Franchitti and a 32-point lead over Dixon, finished 18th and has 562 points.

Graham Rahal finished third, while Danica Patrick, who won here last year, was sixth.

The final race of the season is at Homestead-Miami Speedway on Oct. 10.

Briscoe’s chances of wrapping up the series championship ended when he pitted on the 106th lap. When he came out, a pylon became trapped under his front wheel and he had to head back into the pits to have it removed. He rejoined the race on the 123rd lap but by the time had dropped to 19th.
