Denny Hamlin dominated much of Sunday's Bluegreen Vacations 500 at ISM Raceway, surviving a late restart to win his second race at the track and sixth of the season. The victory puts him in the final four eligible to win the season championship at Homestead-Miami Speedway this week, of which three are Joe Gibbs Racing drivers. Kevin Harvick will be the lone driver outside of that organization with a chance to claim the season title and will have to overcome the Toyota powerhouse that has dominated much of the season so far. Hamlin's Phoenix win made him the only driver among the final four not to have won the series championship yet, but he has won at Homestead twice before. His last title chance came in 2014 and he may have to win again this week to get the job done.
The 2019 season concludes this week in the traditional Miami closer. Winning the title in recent years means winning the race, too. All four drivers have won at the track, but only Hamlin has won more than once. In a season of twists and turns, it's appropriate that the drivers who have won the most races this season are the ones fighting it out for season dominance. It all comes to a close this week in the Ford EcoBoost 400.
