He claimed his seventh win at Charlotte, which broke a tie with Mark Martin for most victories in the series at that track. If Busch wins Saturday's 200- mile race at Dover, he will surpass Todd Bodine and Carl Edwards for most victories (three) here.
A driver from Joe Gibbs Racing has won five of the last seven Nationwide races at Dover. Last year, Joey Logano, in his final season with JGR, won both events at this track.
"This is a favorite track for most in the garage, because it's so unique with the concrete and high banking," Busch said. "JGR has obviously run well here, sweeping both events in 2012. So we have good notes to return with. I have high expectations for this one, since I feel I know the track pretty well and I know (crew chief) Adam (Stevens) has been successful here too. He won both of the races here last year. So I want another stab at it. and this time we can win it together."
If Busch takes the checkered flag at Dover, his seventh win will come in the 11th race of the season. The earliest a driver in Nationwide has captured his seventh victory of a season was in the 16th race of 1984 when Sam Ard won at South Boston (Va.) Speedway.
Kasey Kahne, Matt Kenseth and Logano join Busch as those Sprint Cup Series regulars scheduled to compete in this race.
After posting his eighth straight top-10 finish at Charlotte, Regan Smith holds a 29-point lead over Sam Hornish Jr. in the Nationwide standings.
