MARTINSVILLE, Va. — Brad Keselowski talks as though racing continues to be business as usual. The 28-year-old is leading the standings in NAS­CAR’S Chase for the Sprint Cup, and while his margin over five-time champion Jimmie Johnson is 7 points, and perennial contender Denny Hamlin is only 20 points behind, Keselowski quickly dismisses talk that being chased in the Chase means pressure.

‘‘I feel good about our situation,’’ Keselowski said. ‘‘I love the way we performed the last few weekends, really over the Chase. You want to win every race, but that’s not realistic. We’ve been fortunate to win two races and be in contention in others. Even when we don’t win, we seem to be able to find a way to not have a disaster out of it.’’
