LAS VEGAS -
Penske Racing has signed Brad Keselowski and his crew chief to contract extensions after the duo raced to a fifth-place finish in NASCAR's top series.
Terms of the deals announced Thursday have not been released. Penske says the extensions are for multiple years.
Keselowski just completed his second season with Penske in the Sprint Cup Series. He worked with Wolfe in 2010 to win six races and the Nationwide Series championship, and Wolfe was moved up to the Cup team this season.
Keselowski drove the No. 22 Dodge to three wins this year, a spot in the Chase for the Sprint Cup championship and a career-best finish in the standings.
Keselowski has become one of NASCAR's most vocal drivers and was fined $25,000 two weeks ago.
