Matt Kenseth won Saturday's Aaron's 312 at Atlanta Motor Speedway, holding off a charging Kyle Busch in the green-white-checkered dash to the finish. Then he hopped in his Crown Royal IROC car and did it again, holding off the 11 other racing superstars in what is the equivalent of racing's all-star series, winning both the race and the championship. ¿We had a good day today, for sure," Kenseth said. "My Busch guys did a great job preparing my car for me today. And it was fun to race against those guys in the IROC race. I got a good push from Kurt Busch toward the end.¿ The Aaron's 312 race was red-flagged with three laps to go after local racing sensation Reed Sorenson collected Clint Bowyer, scattering debris. Eighteen-year-old Sorenson, a Peachtree City (Ga.) native and former Legends racing champion at Atlanta Motor Speedway, spent most of the race in the top 10, leading three times for 47 laps. The disappointing late-race crash relegated Sorenson to 29th. ¿I just got into the back of the 21 (Bowyer),¿ Sorenson said. ¿We had a good car all day long. Leading those laps was really exciting.¿ Kenseth took the lead on lap 189 and never relinquished it, despite valiant efforts by Busch. "That's all I had," Busch said. "I couldn't really give him anymore. I didn't say it on TV but my heart and prayers go out to the Hendrick family. I tried the best I could. I didn't only lose a car owner, a spotter, a friend, I lost a brother."
