Kyle Busch took the lead from Joey Logano 18 laps from the end to win his fifth Nationwide race this season and second in three years at Darlington Raceway on Friday night.

The victory also capped a dominant showing by the Busch boys at the track "Too Tough To Tame." Older brother Kurt set a qualifying record to win the pole for the Southern 500 on Saturday night. Kyle was third in Sprint Cup qualifying before dominating the Nationwide race.

The younger Busch started from the pole and was the strongest car throughout. He led for 107 of the 147 laps and finished a second in front of Elliott Sadler. Joe Gibbs Racing placed four in the top five, Busch and Elliott's teammates Brian Vickers third and Matt Kenseth fifth.

Kyle Busch started from the pole — the four JGR racers qualified 1-2-3-4 — and was rarely challenged. Kenseth, a past Nationwide winner here, was the only other driver to lead more than a lap with 27.

Logano was in front when the field restarted following the last of four caution periods while Busch was in third. Busch quickly got past second-place Austin Dillon and began reeling in his former JGR teammate in Logano.

Busch swept past Logano on lap 129 and found mostly clear sailing the rest of the way.

Busch is the Nationwide leader with 56 career wins. He did not win in the series while operating a car he owned. Since rejoining JGR, Busch has regained his dominance. Now, he tries for his third double-double this season at the Southern 500 after sweeping both the Nationwide and Sprint Cup races earlier this season at Fontana and Texas.

Busch won the 2008 Southern 500 at Darlington.

The leading rookie on the Nationwide series, Kyle Larson, finished sixth while series points leader Regan Smith was seventh. Sprint Cup regular Kasey Kahne was ninth.
