NASCAR champions Brad Keselowski and Martin Truex Jr. were among the first four drivers knocked out of the playoffs Saturday night at Bristol Motor Speedway, where Kyle Larson cruised to an easy victory. The first of three elimination races in the 10-race playoffs began with Denny Hamlin, Truex, Keselowski and Harrison Burton all below the cutline facing elimination from the 16-driver field. Hamlin, a three-time Daytona 500 winner with four career wins at the track in Bristol, Tennessee, was never really worried and finished fourth.
