Kiwi IndyCars driver Scott Dixon has finished sixth in this morning's race at Belle Isle in Detroit to hold his championship lead.
The 36-year-old recorded a second place finish in yesterday's race at the same street circuit in inner-city Detroit despite battling a broken bone in his ankle that he picked up in his horror Indianapolis 500 crash a week ago.
Dixon started eighth but lost eight seconds at a pit stop due to an issue refueling his car. He fought his way up a few places to bank some valuable championship points in the second half of the race.
Graham Rahal survived a late red flag that bunched the field up to win the race to complete a double for the weekend. He became the first driver to sweep the weekend in Detroit.
Josef Newgarden was second, Will Power third and Indianapolis 500 winner Takuma Sato fourth.
The series move to Texas Motor Speedway next week.
