Hendrick Motorsports' William Byron won pole position for Sunday's Goodyear 400 at Darlington (S.C.) Raceway (3 p.m. ET, FS1, MRN, SiriusXM NASCAR Radio) -- yet another supreme performance for his NASCAR Cup Series championship-leading No.

Next up at Darlington is an Xfinity Series race Saturday afternoon and Sunday's Goodyear 400, which will be led to green by William Byron.

William Byron said it “sucks” to have lost victory in the closing stages of the NASCAR Cup Series race at Darlington. Byron dominated a major chunk of the Goodyear 400, leading 243 out of 297 laps and winning Stages 1 and 2 after qualifying the #24 Hendrick Motorsports Chevrolet on pole position.
