The No. 18 Toyota driver ended a 21-race winless drought dating to June, scoring his fifth victory of the season.
Busch took the lead on a Lap 170 restart from teammate Denny Hamlin and commanded the final 97 laps as the race stayed green.
“We have a great race team and a great owner and the best sponsor in sports,” Busch told NBC. “Thank you to everyone for this opportunity. I may be the one who hoists the trophy or to have a championship, but it wouldn’t be possible without (crew chief) Adam Stevens, (owner) coach Joe Gibbs, J.D. Gibbs, Coy Gibbs, the whole family. … This (Toyota Racing Development) engine was awesome tonight. It’s been awesome all year, we had one issue. It’s so much fun to work with these guys and this group. Everybody that puts it all together for me. There’s alway your doubters, there’s always your haters. But you know what? This one’s for Rowdy Nation, ’cause you guys are the best.”
