MOORESVILLE, N.C. (AP) -Brad Keselowski will start his new job at Penske Racing a little early.

Keselowski will drive the No. 12 Dodge for the final three NASCAR Sprint Cup races of the season, replacing David Stremme.

Keselowski, who won the Cup race at Talladega in April, signed a deal in September to take over the No. 12 in 2010. Team owner Roger Penske opted to bring Keselowski in ahead of schedule so the driver can get jump start on next season.

The 25-year-old Keselowski is currently ranked third in the Nationwide Series points race while driving for JR Motorsports. He'll drive the No. 22 Dodge for Penske in the Nationwide Series next year.

Stremme was 31st in points through 33 races this season.

Penske announced the change on Monday.
