William Byron avoided a wreck between Ross Chastain and Kyle Larson on a restart six laps from the end and held on to win the Goodyear 400 in overtime at Darlington Raceway on Sunday.

Byron, who got pushed out of the way by winner Joey Logano two laps from the end here a year ago, drove away from Kevin Harvick during a green-white-checkered finish for his third victory of the season and the seventh of his career.

Harvick was second and Chase Elliott third, his best finish since returning to NASCAR from a broken leg while snowboarding.

Brad Keselowski was fourth, followed by Bubba Wallace, Harrison Burton, Kyle Busch, Justin Haley, Ryan Blaney and Chris Buescher.

It was the 100th win for Hendrick Motorsports' No. 24 car and the organization's first victory at Darlington since Jimmie Johnson won the 2012 race.

It looked like 2021 champ Larson or points leader Chastain had the strongest cars and figured to be there at the end. Instead, Chastain was alongside Larson during a restart and admitted trying to squeeze his competitor against the wall in turn two. Both wound up wrecking.

Larson finished 20th and Chastain, who punched Noah Gragson in a pit-road confrontation a week ago at Kansas, was 29th.

Larson moved into the lead when Denny Hamlin went to the pits with 30 laps remaining and was in prime position for victory until tangling with Chastain.

Martin Truex Jr. started from the pole and led 146 of the first 151 laps before he was clipped by Chastain at the end of stage.

Next week is the NASCAR All-Star Open at revamped North Wilkesboro Speedway in North Carolina. The 0.625-mile short track was a regular on the NASCAR schedule from 1949 through 1996 before the series left. But after a spirited effort to revive the old, country track, owner Speedway Motorsports would host the all-star race as part of NASCAR's 75th anniversary celebration.
