As Joey Logano circled Bristol Motor Speedway, he'd briefly glance in the mirror to watch Kevin Harvick.
Logano had taken the lead on a restart with 64 laps remaining, but Harvick was closing in by using a completely different line. Refusing to get rattled, Logano stuck to what worked for him Saturday and won the Bristol night race for the second consecutive year.
Logano has won on a superspeedway in the Daytona 500, on the road course at Watkins Glen and now Bristol's short track. He has won twice this month as he readies for the start of the Chase for the Sprint Cup championship.
Logano led 176 laps, second only to Joe Gibbs Racing driver Kyle Busch, who led a race-high 192 laps.
Harvick finished second for the 10th time this season. The reigning Sprint Cup champion has a career-best 17 top-five finishes this year and had his 250th career top-10 finish in 526 starts.
Although Busch dominated early, he had faded a bit as the laps clicked off. Then he was hit with a speeding penalty on the final round of pit stops and finished eighth. Edwards led 74 laps but had a tire go flat when he was out front and it cost him two laps.
He finished seventh.
