In the each of the past two seasons, the driver who would become IRL IndyCar Series champion has snatched Indianapolis 500 victory away from the sentimental favourite in the closing moments, as Dan Wheldon beat Danica Patrick in 2005, and Sam Hornish Jr overcame the Andretti family with a last gasp push a year ago.
In 2007 it already looks like Wheldon is on course for another championship title, and a second Indy win would bring him a lot closer to that goal. But at least nine other drivers believe they might be able to stop him when the 91st Indy 500 begins on Sunday.
There was nothing to choose between Penske and Ganassi during the 2006 season, but this year Ganassi, and particularly Wheldon, have moved a step ahead. The Briton has led 70 percent of the laps in the three oval races so far, and only radio problems in Motegi prevented him from taking a hat-trick of dominant wins.
