Harvick has won the Atlanta race in NASCAR's second-tier series three years in a row and four times overall.
Logano has been the runner-up the last two years.
No one else was even close on this day.
"It seems like I finish second on this track all the time," said Logano, who came up just short of a victory from the pole. "I'm going to keep running this Xfinity Series race until I win it."
Good luck beating Harvick, the defending Sprint Cup champion and a 45-time winner in the Xfinity cars.
In Atlanta, he's especially tough, having mastered the art of running strong at the bottom of a track that is infamously rough on tires.
“He's a great talent,” said
Harvick won a race off pit road under yellow with 27 laps to go, which proved to be crucial in holding off Logano. On the restart, Harvick had the prime inside position, and Logano's bid to pass from the outside was thwarted when Chase Elliott gave Harvick a bit of a nudge.
"That pit stop was what won the race," Harvick said.
Logano made one last push for the front. A vibrating right rear tire ended any hope of catching Harvick, who won by 1.207 seconds with an average speed of 149.813 mph.
"Once it got really bad, I couldn't keep up with Kevin anymore," Logano said. "It just kept getting worse."
