A surprising but not unpredictable finish to the Indy Grand Prix of Sonoma when rookie Marco Andretti became the youngest driver in IRL IndyCar Series history to pick up his first career victory with a fuel saving strategy on Sunday.
The points contenders had an up and down day with mixed finishing results, now points leader Helio Castroneves finished 5th while his teammate and now second in points Sam Hornish Jr. battled back to finish in 9th position.
Leaving Sonoma, the points chase has tightened to just 1 point between first and second place and Penske Teammates with Ganassi Racing 19-21 points back. Now there's just one race to go, the season finale, the Showdown at Chiacgoland on September 10th.
