DARLINGTON, S.C. —
Ty Gibbs was second, Josh Berry third and Denny Hamlin fourth. Chase Briscoe was fifth followed by William Byron, Bubba Wallace, Justin Haley and Michael McDowell.
It was another near miss for Buescher, who lost by 0.001 seconds to Kyle Larson at Kansas in the closest finish in NASCAR history.
Buescher slid to 30th and Reddick 32nd at Darlington.
Buescher confronted Reddick when both got out of their cars. Reddick took full blame for the incident.
Larson was in the top 10 when he spun out with 40 laps left and could not return.
Meanwhile, one slipup ended the chances of two NASCAR champions. Ryan Blaney, Martin Truex Jr. and Byron were three-wide on Lap 128 when Byron tagged Truex, who pushed into Blaney and sent him against the wall in Turn 2.
The crew for Blaney, the defending Cup Series champion, could not repair the damage, and his day was done. He rode up alongside Byron to signal his displeasure with Byron’s move.
“He used a little bit more racetrack than I thought, so I have every right to be mad, and he gets away scot-free,” said Blaney, who wound up last in 36th place.
Truex, the 2017 series champion, dropped from the top 10 and finished 25th.
