Dario Franchitti became the second Scotsman to win the Indianapolis, claiming victory in a rain-shortened 91st running of "The Greatest Spectacle in Racing."

The Andretti Green Racing driver, who joins Jim Clark as the only Scottish drivers to win the race, inherited the lead on Lap 155 when teammate Tony Kanaan pitted, and the No. 27 Canadian Club Dallara/Honda/Firestone splashed across the finish line under the yellow/checkered flag combination on Lap 166 as rain doused the cavernous facility.

"Who would have thought it?" said Franchitti, whose rain-soaked firesuit didn't dampen his enthusiasm as he chugged the traditional winner's bottle of milk in Victory Circle. "I can't believe it. It's the Indianapolis 500."

Target Chip Ganassi Racing's Scott Dixon was runner-up, while pole sitter and two-time 500-Mile Race winner Helio Castroneves of Team Penske finished third. Sam Hornish Jr., who last year gave team owner Roger Penske his 14th Indy 500 title, finished fourth and Ryan Briscoe in the No. 12 Luczo Dragon Racing car (a Team Penske satellite program) rounded out the top five.

The 2007 edition of "The Greatest Spectacle in Racing," played out before a boisterous crowd of more than 250,000, had numerous turns that determined the finish order.

Race Day started and ended with rain. Though the 33 cars took the green flag from honorary start Peyton Manning at the appointed time, the red flag flew on Lap 113 because of a cloud burst that enveloped the racetrack. After a 2-hour, 57-minute delay, Kanaan led the field to the green flag. During the three pace laps, Franchitti pitted because of a right-rear tire puncture.

AGR drivers -- Kanaan, Danica Patrick and Marco Andretti -- took turns on the point during the ensuing 20 laps (Kanaan leading Patrick by 0.4277 of a second on Lap 135). But when the teammates, who last pitted on Lap 100, ducked in for 22 gallons of ethanol and four Firestone Firehawks under green on Lap 137, Franchitti assumed the lead.

It was Jaques Lazier's turn to move to the front when Franchitti pitted on Lap 143, but Kanaan was the leader on Lap 150 (4.1198 seconds ahead of Hornish and turning a lap of 222.645 mph). It was under yellow (single-car crash in Turn 3 involving the No. 25 Roth Racing entry) when Kanaan's No. 11 Team 7-Eleven rumbled onto pit lane. Franchitti again assumed the lead, with Dixon on his tail and Briscoe not far behind.

The deal was sealed on Lap 163 when a multi-car crash on the backstretch, sparked by the Nos. 10 (2005 winner Dan Wheldon) and 26 (Marco Andretti) cars touching wheels. The cars of Ed Carpenter and Buddy Rice also were involved. As the Delphi Safety Team was clearing the racetrack, the skies opened.

Scott Sharp (No. 8 Patron Sharp Rahal Leterman Racing), Tomas Scheckter (No. 2 Vision Racing), Patrick (No. 8 Team Motorola), Davey Hamilton (No. 02 HP Vision Racing) and Vitor Meira (No. 4 Delphi Panther Racing) filled out the top 10.
