Logano looked set for the win as he built a small gap to Dillon, but the #3 car went deep to spin the leader out and then immediately cut down the track to spin the fast-finishing Denny Hamlin.
Dillon defended his starring role in the last-lap mayhem, saying simply 'I hate to do that, but sometimes you just got to have it.'
The fallout from the incident may have been far greater had Hamlin and Logano not already been firmly ensconced in the playoffs, meaning that Dillon's actions didn't ruin their chances of making the postseason.
