Mooresville, NC -- (Sports Network) - Penske Racing announced Monday that Brad Keselowski will replace David Stremme in the No.12 Dodge for the final three Sprint Cup races of the year, beginning this weekend at Texas.

Two months ago, Penske named Keselowski the full-time driver of the No.12 car for the 2010 Sprint Cup campaign. The 25-year-old driver already has run a limited Cup schedule this year with Hendrick Motorsports and Phoenix Racing. He is currently third in Nationwide Series points, driving the No.88 Chevrolet for JR Motorsports, which is co-owned by Dale Earnhardt Jr. and Rick Hendrick.

"Penske Racing wants to give Brad an opportunity to work with the team and get to know the race car as we prepare for the 2010 season," team owner Roger Penske said in a statement. "These three races will provide a good base for both Brad and the team as we head into next year. Penske Racing also thanks David Stremme for his contributions to the team this year. We wish David the very best moving forward."

Keselowski won his first career Cup race in April at Talladega. He finished eighth there Sunday.

"We all have high expectations for next season and beyond, and being able to race with the team this year will only help us as we look toward 2010," Keselowski said.

Stremme, currently 31st in Cup points, has yet to score a top-10 finish in 33 races. He has driven for Penske since the start of this season.
