Logano took the Stage 1 win under caution after Erik Jones (Joe Gibbs Racing) and Brad Keselowski (Team Penske) suffered a nasty accident on the exit of Turn 2.
The duo made side-by-side contact in the middle of the turn that sent both into the outside wall before Keselowski ricocheted into an infield tyre barrier.
The Penske driver quickly jumped out from his stricken car with both drivers walking away unharmed.
In the hunt for one of two playoff spots, Jimmie Johnson initiated an eight-car wreck on Lap 106 after his Hendrick Motorsports entry got loose in the middle of Turn 2.
The seven-time champion sustained too much damage to continue, leaving him without a spot in the playoffs for the first time in his career.
Clint Bowyer (Stewart-Haas Racing), who finished fifth, and eighth-placed Ryan Newman (Roush Fenway Racing) secured the remaining two playoff positions heading into the final 10 races of the season.
Darrell Wallace Jnr (Richard Petty Motorsports) finished third and William Byron (Hendrick Motorsports) fourth.
The playoffs begin at Las Vegas Motor Speedway on September 13-15 (local time) with the first of three Round of 16 races.
