Marcos Ambrose looking for a win at Sanoma

Marcos Ambrose wants nothing more than to break Hendrick Motorsports' four-race winning streak.

His best shot comes Sunday on the road course at Sonoma Raceway.

A win could earn the Australian his first berth in the Chase for the Sprint Cup championship and solidify his future at Richard Petty Motorsports. Ambrose's current deal with the organization is up at the end of the season.

In his fourth season driving for the Petty organization, Ambrose has two career Sprint Cup victories.

Both wins were on the road course at Watkins Glen.

He's still looking for his first victory at Sonoma, where Ambrose is always considered one of the favorites but hasn't managed to grab the checkered flag in six starts.
