DARLINGTON, S.C. (AP) -- Denny Hamlin overcame a bad miss of the pit road entrance to chase down Martin Truex Jr. with three laps left to win the Southern 500 at Darlington Raceway on Sunday night.
Hamlin checked up after sliding by the entrance with 54 laps left and fell behind Truex by 20 seconds. But Hamlin slowly reeled in Truex and passed him when his rival brushed the wall and got a flat tire.
Hamlin swept throwback weekend at Darlington after winning the Xfinity race Saturday. Truex won the first two stages, clinching NASCAR's regular-season championship and gaining the No. 1 seed heading into the playoffs in two weeks.
Truex has the most playoff points of any driver. Not including points for where drivers finish in the regular-season standings, Truex has 37 playoff points -- 17 more than second-place Kyle Busch, who finished second in Sunday's race. Kurt Busch was third. Austin Dillon finished fourth, and Erik Jones was fifth.
