INDIANAPOLIS (AFP) - American Alexander Rossi, a former Formula One test driver in only his sixth IndyCar race, won the 100th Indianapolis 500 on Sunday, nursing fuel over the last 36 laps for the victory.

The 24-year-old Californian spent three years as an F1 test driver before racing five times in the series last year. He switched to IndyCar this year but was never better than 10th in the series until taking his historic 200-lap triumph on the 4km Indianapolis Motor Speedway oval.

"I have no idea how we pulled that off," Rossi said. "I just can't believe we have done this. It's an amazing result."

Colombia's Carlos Munoz finished second as he did in his 2013 Indy debut with American Josef Newgarden third and Brazil's Tony Kanaan, the 2013 Indy 500 winner, in fourth.

Rossi was ninth on the final restart and fearful he would not have enough fuel to reach the checkered flag.

But as rivals ahead of him went back to the pits for a splash in the tank, Rossi drained the final drops long enough to win, his car running out of fuel seconds later and rolling to a stop in the fourth turn.

"I'm just so thankful for doing this on the 100th running," Rossi said. "We rolled the dice and made it happen. I'm at a loss for words. It will change my life."

Rossi became the ninth Indy 500 rookie to win, the first since Brazil's Helio Castroneves in 2001.

It was the second Indy 500 triumph for car owner Bryan Herta, who merged his team with that of Michael Andretti this year. Herta won in 2011 with the late British racer Dan Wheldon and felt his former driver's spirit as he looked and pointed to the heavens.

"I want to thank DW," Herta said. "Man, it was so close at the end and for a rookie to drive with the poise (Rossi) did in that situation, it was incredible."


Munoz took the lead with 10 laps remaining but five laps later was forced into the pits. He needed only four seconds to add enough fuel to reach the end.

That put Rossi in front with his crew saying by radio he had a half-lap edge on Munoz and should nurse his fuel in the final turns.

"I knew I had this one. The car was flying," Munoz said. "For half a lap's worth of fuel we would have made it.

"One thing is clear - I will win the 500 one year." Newgarden settled a career-best Indy finish but was denied the full-speed shootout for victory he wanted.

"It was a tough day," he said. "I really think we had a shot. We had the car to win. It just didn't fall our way. It's just a tough pill to swallow.

"Didn't have enough at the end. I knew we could outrace people. I really wanted to have a shootout." Kanaan overcame being struck in the hands by debris from a crash and his car being hit in the pit lane by Australian rival Will Power, but like Newgarden had to stop late for fuel to doom his title bid.

An unprecedented sellout crowd of more than 350,000 people watched the 33-car field.

Canadian pole sitter James Hinchcliffe, nearly killed in a practice crash last year, finished seventh.

At the end of the pit lane on lap 117, three-time Indy 500 winner Castroneves's car was struck on the left side by that of US driver Townsend Bell, whose car bounced left and into compatriot Hunter-Reay, collecting three of the fastest cars to that point.

Castroneves escaped and moved to the front while Bell and Hunter-Reay needed repairs and fell back for good.

But Castroneves's left rear wheel guard came loose after being struck by J.R. Hildebrand and required repairs, taking the Brazilian out of contention.

France's Simon Pagenaud, who won the previous three IndyCar races - all on road courses - to seize the season points lead, finished 19th.

Britain's Stefan Wilson finished 28th out of 33 drivers that made it to the final lap.
