Kiwi driver Scott Dixon’s charge to defend his Indycar crown has come to an end after he finished 13th in this morning’s penultimate race of the championship at Leguna Seca in California.

Colton Herta won the race with Dixon’s Chip Ganassi teammate Alex Palou finishing second to extend his title lead and eliminate Dixon from the equation.

Starting eighth, Dixon moved up some spots during the opening stint of the race to be third at one point. He went a different way strategy-wise at his first pit stop, taking the black tyres, and his rivals took advantage to push him down the order.

But his chance of returning serve during the next stint and staying in the title battle going to the final round were given a major hit when Takuma Sato spun in front of the Manurewa junior and then knocked the six-time series champion off the track.

It is not the first time Sato has taken Dixon out.

Palou will take a 35-point lead over Pato O’Ward to the final at Long Beach next weekend with Josef Newgarden the only other driver mathematically still in the hunt.

Dixon is fourth in the standings.
