DARLINGTON, S.C. — Kyle Larson won Saturday’s NASCAR Xfinity Series race at Darlington Raceway after bumping challenger John Hunter Nemechek during a fierce battle on the final lap.

Larson recovered from a pit-road speeding penalty that dropped him from the lead pack to 31st and moved into position to challenge for the win in the closing miles.

He and Nemechek raced hard on the final lap, running side by side and touching. Nemechek almost lost control but managed to challenge Larson in the final turn before Larson bounced off the wall and hit Nemechek. Larson raced under the checkered flag as Nemechek lost control of his car.

A debris caution with 22 laps to go in the race eliminated Nemechek’s three-second lead over Justin Allgaier and bunched the field.

The restart found Nemechek, Allgaier, Cole Custer, Austin Hill and Kyle Larson at the front.

Nemechek jumped out to a lead on the green flag, but another caution brought the field together again.

Allgaier finished second and was followed by Cole Custer, Austin Hill and Nemechek.

Much of the field was involved in a multi-car crash on Lap 67. With the field bunched after a restart, contact between Sheldon Creed and Nemechek in Turn 3 sent Creed into a spin, and cars behind them were swept into the accident. A dozen cars were impacted in a crash that looked Talladega-like. Nemechek drove away from the accident with no significant damage.

Larson won the first stage, finishing in front of Nemechek, Hill, Custer and Sam Mayer.

Mayer led much of the stage, but a late-stage caution flag opened the door for Larson to move into first place.
