SAO PAULO, Brazil -- Will Power overcame wet track conditions and poor visibility to win the Itaipava Sao Paulo Indy 300 for the second year in a row.
Persistent rain and standing water on the 2.536-mile Sao Paulo street circuit forced Sunday's scheduled 75-lap race to be postponed for a day. Fourteen laps were completed before IZOD IndyCar Series officials pulled the plug. Officials also placed a two-hour time limit on the event.
Power, who has started on the pole in each of the first four races this year, took the lead for good when Takuma Sato pitted and relinquished the top position with less than 10 laps remaining. Power finished 4.7 second ahead of Graham Rahal for his second win of the season. He won the inaugural race in Brazil last year.
"I'm really happy to get the car in victory lane again," Power said. "I've been on pole four times and had two wins, so it's a great start."
There was one hour and 19 minutes remaining when the race resumed on Monday, with Power leading the way. Light rain continued to fall on the circuit.
Sato overtook Power for the lead after a restart on lap 25. Power pitted under caution on lap 36 and restarted in eighth.
"It was a matter of keeping calm and getting past people without any mistakes and then pulling a gap to be safe," Power added.
Power claimed his 11th overall win in major open-wheel racing. All of his victories have come on road/street courses.
Rahal held off a hard-charging Ryan Briscoe in the closing laps.
"We were lucky to be quick enough there at the end that we were able to keep up with Will but not let Ryan close in, because we had to save a lot of fuel," Rahal said.
Briscoe, who is Power's teammate at Team Penske, finished third, while Dario Franchitti, the two-time defending series champion, recovered from a mid-race spin to take the fourth spot. Franchitti slid off course heading into turn one and plowed into the tire barrier. He suffered damage to his front wing.
"We came out of this with a fourth-place result, so I'll take it," Franchitti said.
Oriol Servia finished fifth, followed by Mike Conway and Justin Wilson. Sato wound up eighth.
"After our pit stop, we had fuel issues and did not make it, which caused a real problem in the end," Sato said.
Rookie drivers James Hinchcliffe and J.R. Hildebrand completed the top-10.
Helio Castroneves, Tony Kanaan and Danica Patrick were all involved in a multi-car accident during the opening lap of the race on Sunday. Castroneves, Kanaan and Patrick ended up finishing 21st, 22nd and 23rd, respectively.
With the win, Power took a 14-point lead over Franchitti.
The next IndyCar race is the May 29 Indianapolis 500 -- the 100th anniversary of the prestigious event.
