FORT WORTH, Texas (AFP) - New Zealand's Scott Dixon continued his dominant 2008 form Saturday with a victory under the floodlights in IndyCar racing's Bombardier Learjet 550.

Dixon started from pole position and claimed his third race of the season - his first since his triumph in the fabled Indianapolis 500.

The 27-year-old capitalize on a late crash involving Marco Andretti and 2007 Rookie of the Year Ryan Hunter-Reay to cross the finish line as an Indy Racing League race ended under caution for the second week in a row.

After Dixon passed Andretti with six laps to go, Hunter-Reay - who was in third - collided with the 21-year-old Andretti on lap 224, causing both racers to hit the wall. Andretti finished 19th, while Hunter-Reay was 20th.

While Texas Motor Speedway crews tried to collect the two damaged vehicles, Dixon cruised across the finish line.

Brazil's Helio Castroneves came in second, while Ryan Briscoe - who beat Dixon in last Sunday's race in Wisconsin, was third.

It was Castroneves' seventh straight top-five finish on the circuit.

Dan Wheldon and Tony Kanaan rounded out the top five, while Japanese rookie Hideki Mutoh came in sixth. Indy Japan 300 winner Danica Patrick finished 10th.
