NASCAR points leader Brad Keselowski says he's scaling back his Nationwide Series schedule to focus on winning the Sprint Cup championship.

Keselowski says he will not run the Nationwide race at Kansas later this month. Penske Racing will instead have Ryan Blaney run the event.

Keselowski said Tuesday during an appearance at Charlotte Motor Speedway he'll evaluate the rest of his Nationwide schedule as the season winds down. He is leading the Chase for the Sprint Cup championship with seven races remaining.

Keselowski picked up his second win of the Chase on Sunday at Dover. He takes a five-point lead over five-time champion Jimmie Johnson into this weekend's race at Talladega.
