New Zealand motor racing driver Scott Dixon has kept alive his hopes of a fifth Indycar title finishing second in the penultimate race of the season at Watkins Glen road circuit in New York state.
It lifts the four-time champion to within three points of series leader American Josef Newgarden with just the double points race at Sonoma Raceway near San Francisco in a fortnight remaining.
The race was won by American Alexander Rossi from pole position as he went on to win his first Indycar race.
Penske driver Newgarden hit the wall as he came out of the pits late in the race and was forced back in to make repairs eventually finishing 18th.
A fuel filling problem may have cost Dixon the race.
"I locked up the tires on the first stop and I don't think we got any fuel. We had to save fuel on the next stint as a result and battled our way back," he said.
"I think we passed a lot of cars today and it was fun to contend with (Alexander) Rossi there for the win."
