The third race of the IRL season and last event before the on set of the merger was history in the making. The Indy Japan 300 was a difficult race to get off the ground though, as rainy conditions cancelled qualifying and caused postponement of the race start.
Twin Ring Motegi will now forever be the site where the first female driver won an Indy Car event. Danica Patrick sealed the deal after passing Helio Castroneves with 2 laps to go in the 200 lap race. The historical event was made possible through excellent planning and strategy on the part of the Andretti Green team. Danica sat in fourth with 4 laps to go, but fuel starvation forced Dan Wheldon and Tony Kanaan into the pits. Fuel level was also an issue with Castroneves, he was in conservation mode in the final laps. Thanks to the efforts of her crew, Patrick had enough fuel to maintain speed throughout the race and take her first, and hopefully not last, win in the big leagues.
