Mooresville, NC (My Sportsbook) - Brad Keselowski has signed an agreement with Penske Racing to compete full-time in both the Sprint Cup and Nationwide Series, beginning in 2010.

Keselowski, 25, will replace David Stremme in the No.12 Dodge for next year's Sprint Cup campaign. The 25-year-old Rochester Hills, Michigan native has run a limited Cup schedule this year with Hendrick Motorsports and Phoenix Racing. He is currently third in Nationwide points, driving the No.88 Chevrolet for JR Motorsports, which is co-owned by Dale Earnhardt Jr. and Rick Hendrick.

"We are very excited to welcome Brad to the Penske Racing family," team owner Roger Penske said. "Brad has shown terrific success on track the past several years and has quickly established himself as one of the top young stars in racing. He comes from an impressive family background in motorsports. He is a proven winner and a welcome addition to our team."

Keselowski has recorded one victory and three top-10 finishes in 10 career Cup starts so far. His win in the April 26 race at Talladega came in just his fifth start.

"Penske Racing is one of the top teams in all of motorsports, and I am honored to join Roger Penske's organization and compete for wins with his Cup and Nationwide Series teams," Keselowski said. "This is a great opportunity for me to continue competing in the Nationwide Series and to run my first full season in the Cup Series with a strong and experienced team."

Penske Racing has accumulated 63 wins since the organization began competing in NASCAR's top division in 1972. Penske fields Dodges for drivers Kurt Busch, Sam Hornish Jr. and Stremme in the Cup Series.

A third generation driver, Keselowski has won at every racing level in which he has competed. He grew up working for his family's team, K Automotive Motorsports. His father, Bob, won more than 50 races and captured an ARCA Series championship during his 23-year driving career. The younger Keselowski joined NASCAR in 2004, racing for his family's team in the Truck Series.

There is no word yet on Stremme's status with the team for next year.
