 The race also served as the halfway mark for the battle for entry into the 2007 Chase for the Nextel Cup.This race also marked the first time since Daytona that Michael Waltrip raced on Sunday, or because of the rainout, a Monday.In a twist of irony, Waltrip's teammate, David Reutimann, who had out-qualified or bumped his boss from the field many times before, failed to qualify for his second consecutive race.
