Kevin Harvick punched his ticket into the Eliminator Round for the Sprint Cup championship by winning Saturday night's Bank of America 500 at Charlotte Motor Speedway.  He beat second-place finisher Jeff Gordon to the line by 0.6 seconds.  It was the third win of the season for Harvick but his first time in victory lane for a Sprint Cup Series race since April at Darlington.  He joined Joey Logano as the drivers who have clinched a spot in the Eliminator Round.  Post-race, tempers flared in the garage area where Denny Hamlin had to be restrained from getting into a physical altercation with Brad Keselowski, and then moments later, Matt Kenseth and Keselowski were involved in a brawl in between a pair of Team Penske haulers.  During the final two laps, Keselowski and Hamlin had tangled multiple times while battling for position.  Keselowski retaliated against Hamlin after the checkered flag had waved by bumping him from behind and attempting to spin him out.  The Geico 500 at Talladega Superspeedway is up next Sunday.
