SAO PAULO — Will Power made a late overtaking move to take the lead from Ryan Hunter-Reay to win the rain-shortened IndyCar season opener on the streets of Sao Paulo on Sunday.

The Australian passed the American with three laps to go, clinching the inaugural Sao Paulo Indy 300 for his second career victory.

Power crossed the line 1.858 seconds ahead of Hunter-Reay when the race ended at the two-hour time limit with only 61 of the 75 scheduled laps completed.

The race had to be red-flagged near its halfway point after heavy rains made track conditions unsafe, marking another setback for the track which was initially being hailed as one of the highlights of the season but faced problems throughout the weekend.

Home crowd favorite Vitor Meira was third, followed by compatriot Raphael Matos at the 2.6-mile, 11-turn Anhembi temporary circuit in South America's biggest city.

Danica Patrick lost control of her car as it started raining, finishing 15th.

Power, whose other victory was last year in Edmonton, got out of his car and celebrated with the thousands of fans packing the grandstands of the stadium-like Sambadrome where the race took place.

"I feel awesome," the Penske driver said. "We battled it out, it was a great day."

There were only about three minutes left when Power overtook Hunter-Reay.
