UNDATED (AP) - Coming off a strong third-place performance at Kentucky Speedway last week, Marco Andretti is the only driver on his father's race team still unsigned for next season.

The Andretti Green Racing team also includes Tony Kanaan, Danica Patrick and rookie Hideki Mutoh.

The son of Michael Andretti says he wants to sign a new contract as soon as possible. And his father is just as certain that Marco will remain a part of the team. Michael Andretti says Marco is on the verge of being a major contender in every race.
