Mario Haberfeld and Walker Racing had a busy weekend as the Champ Car World Series visited the 1.5-mile oval at the Las Vegas Motor Speedway, but even after their best efforts, 14th place in the Bridgestone 400 Presented by Corona was all they were rewarded with.

Herdez Competition teammates Ryan Hunter-Reay and Mario Dominguez and Walker Racing's Mario Haberfeld have all added their names to the growing list of drivers who will cycle their way around the 4.048-mile Road America circuit on the day before this year's Champ Car World Series event.
