Scott Dixon won the last race of the IndyCar season to move into top spot
Dixon is now in first place ahead of Target Chip Ganassi teammate Dario Franchitti and Ryan Briscoe.
Dixon recorded his fifth win of the season finishing 1.4475 seconds ahead of Franchitti. He led 139 of 200 laps after starting from the pole.
Briscoe went into Saturday's race with a 25-point lead over Franchitti and a 32-point lead over Dixon, but lost control of his car after leaving the pit on a yellow flag. He swerved to the left, ran over the large cone marking the end of pit lane and sideswiped the inside wall, with a pylon getting stuck under his car's left front.
Because he was leading when the yellow came out, the field slowed to allow Briscoe to keep the lead. But he pitted twice, once to have the pylon removed and another time for repairs, meaning Dixon was back in the lead when the race restarted on lap 118.
Briscoe finished 18th.
Dixon now leads the standings with 570 points followed by Franchitti, who has 565.
"We needed to get maximum points today and we did," Dixon said.
“A fantastic day for Team Target. A 1-2. For me it's tremendous. It's a track I've always wanted to win in. I kind of put Motegi just below the Indy 500. It's a very difficult circuit. I remember coming here in the early years and competing for different engine manufacturers and how much emphasis is put on this race. If you have a fast car, you can still get to the front. Put on a good show. Over the moon. Definitely a good day for points and very happy.”
