Jimmie Johnson goes for his 10th Martinsville victory today but will start at the rear because he spun in qualifying and will need to change tires as well as change the gear and axle. Richard Petty owns the record for most Martinsville wins with 15, followed by Darrell Waltrip (11) and then Johnson and Gordon with nine. Johnson has won in 29 percent of his Martinsville starts, the best of those four.(ESPN)
