Florida:Dale Earnhardt Jr could have been forgiven on Monday if all he wanted to do was relax and enjoy his Daytona 500 victory of the day before. But he slipped on his driving uniform and returned to work, weary from lack of sleep and drained emotionally - and promptly won yet again. The Hershey's Kisses 300 Busch Series was postponed on Saturday by rain after just 31 of 120 laps at Daytona International Speedway. Monday's race was marred by a nine-car crash just 10 laps after the restart. No injuries were reported. Earnhardt regained the lead on lap 85, gave it up twice briefly, then pulled away from everyone except Johnny Sauter. The rest of the field contested a series of side-by-side battles and slipped behind. Earnhardt drove across the finish line 0.135 seconds - about two car-lengths - ahead of Sauter. Asked how much rest he got on Sunday night after winning NASCAR's biggest race, Earnhardt raised a smile. "I was real focused. I could have done an all nighter. It's awesome. It's like a little bonus action to be able to get up on Monday and do a little driving after winning the Daytona 500. This is almost like extra credit," said Earnhardt. "Well, it just seems to keep getting better. I just really enjoyed the victory we got yesterday at the Daytona 500. I mean that's always going to go down as the biggest win in my career. I didn't think I could ever top the Winston that I won in my rookie season. But winning the Daytona 500 is a feeling like no other," he held. He added Monday's win to victories in the Daytona 500 Sunday and in one of the twin 125-mile qualifying races on Thursday. On top of that, Earnhardt finished second in the Budweiser Shootout, qualified third in time trials for the 500 and nearly added a victory in the Rolex 24 sports car endurance racing.
