In the Monster Energy NASCAR Cup Series, the race-winning team of the No. 4 Stewart-Haas Racing Ford driven by veteran Kevin Harvick had one unsecured lug nut in post-race inspection. Crew chief Rodney Childers was fined $10,000 for the safety violation. No further fines or suspensions were placed on the team.

After a flat tire during Stage 1, John Hunter Nemechek battles back to finish 4th in his NASCAR Xfinity Series debut at Atlanta Motor Speedway in Saturday's Rinnai 250.

Although Christopher Bell did not dominate Atlanta nor win the race, he turned some heads after Saturday’s race. Last year’s Truck Series champion only led 12 laps in his No. 20 Joe Gibbs Racing Toyota but finished third and presented speed and experience behind the wheel.

Kevin Harvick surged to the front on a one-lap shootout to end Stage 1 and rolled to a dominating win in Saturday's Rinnai 250 at Atlanta Motor Speedway. Harvick has won the Xfinity Series race at AMS four of the last six years and five times overall.

After taking on the high banks of Daytona to kick off the season, the Monster Energy NASCAR Cup Series, NASCAR Xfinity Series and NASCAR Camping World Truck Series are off to Atlanta Motor Speedway for a tripleheader weekend. Check out the tentative full schedule below, subject to change.

Tyler Reddick came out on top in the PowerShares QQQ 300 at Daytona International Speedway. In what became NASCAR's version of 'Survivor' with a new record of five overtimes, he battled his JR Motorsports No. 9 Chevrolet against a very determined Elliott Sadler for the win.

Exactly one year ago, William Byron stood in victory lane at Homestead-Miami Speedway, having won the NASCAR Camping World Truck Series season-finale the week after his title hopes went up in smoke with his engine. Today, a week after he punched his ticket with a victory in the Arizona desert, he dueled it out with JR Motorsports teammate Elliott Sadler in the final laps of the 2017 NASCAR XFINITY Series season to claim the championship in his name.

Cole Custer led all but 18 laps on his way to dominating and winning the NASCAR XFINITY Series Ford EcoBoost 300 at Homestead-Miami Speedway.

All three series head to Homestead-Miami Speedway this weekend to crown their champions. The Camping World Truck Series finale will air on FS1 Friday evening, followed by the XFINITY Series race Saturday afternoon on NBCSN. Sunday the Monster Energy NASCAR Cup Series will hit the track for the title event at 3 p.m. on NBC to determine its 2017 champion.

Despite a last-minute rag-tag pit crew, due to extraneous circumstances, William Byron took advantage of a late caution to exit pit road ahead of the dominant driver of the race and drove on to win the NASCAR XFINITY Series Ticket Galaxy 200 at Phoenix Raceway.
