Nineteen-year-old Corey Heim of Marietta raced to his first NASCAR Truck Series victory Saturday at Atlanta Motor Speedway in Hampton, getting a push from the lapped machine of John Hunter Nemechek to deny Chandler Smith a second straight win.

Coming off a victory at Las Vegas, Smith — another 19-year-old from the Peach State — took the white flag with the lead on the outside, just ahead of Kyle Busch Motorsports teammate Heim hugging the line at the bottom the track.

Nemechek, also racing for KBM, looked as if he was going to follow Smith, only to dart suddenly to the inside to follow Heim. That was all the youngster needed to zip by Smith and take the checkered flag.

“I can’t believe it,” said Heim. “It’s so surreal to be at my home track. I’ve been coming here since I was 2 years old to watch Cup races.”

Ben Rhodes was second, 0173 seconds behind the winner. Smith settled for a fourth-place finish.

“I would like to have duked it out the 51 (Heim) and have nobody in the middle of it,” said Smith, a three-time truck winner. “That’s the first win for Corey. I’m excited for him. I remember what it was like when I got my first one.”

It was an interesting decision by Nemechek, who had to choose between his teammates. He went with Heim, a part-timer for the team, rather than Smith, who has a full-time ride.

Nemechek finished 24th, two laps down.

“There were no team orders,” Heim said. “As long as one KBM truck won, that’s all that mattered. All the credit to John Hunter Nemechek for giving me help there.”

Smith started from pole in the first race at the 1.54-mile Atlanta track since it was redesigned, with higher banking, narrower curves and a new surface.

Qualifying was canceled after storms hit the track Friday, forcing a much-needed practice session to be pushed back to Saturday morning.

Hailie Deegan had another tough day, finishing last in the 36-truck field after a frightening incident on pit road.

Her left rear tire caught fire after she came in to change her second flat of the race, forcing her behind the wall with just 24 laps completed.

Deegan was pulled from the machine by her crew as it filled with smoke. She was checked and released from the infield care center.

Gibbs steals Xfinity race

Ty Gibbs pulled off a brilliant move after taking the white flag to lead his only lap of the day, winning the NASCAR Xfinity Series race.

On the second attempt to finish the crash-marred race in overtime, Ryan Sieg had the lead in the outside lane with Austin Hill running just inside his bumper.

Hill briefly grabbed the lead in the backstretch before Sieg reclaimed the top spot coming to the line with one lap to go.

But Gibbs, getting a big push from A.J. Allmendinger, spotted an opening between the two leaders, veered left to slip between their cars and got clear of both heading into the first turn.

Gibbs came off the second turn with a lead of several car lengths while a gaggle of machines bunched up behind him, none of them able to make any sort of run.

Gibbs took the checkered flag ahead of Hill by 0.178 seconds. Allmendinger wound up in third, while Sieg dropped all the way back to 10th.

It was another heartbreaking Atlanta finish for Hill, a native of Winston, Georgia about 50 miles west of the speedway. He has finished second twice in truck races at the 1.54-mile trioval. Now, he’s got another runner-up showing in the Xfinity Series.

The 251-mile race brought out 10 caution flags and wound taking almost 2 hours, 40 minutes to complete, finally finishing under the lights after nine extra laps.
