DAYTONA BEACH, Fla. — Denny Hamlin almost couldn't help himself at the start of his Daytona 500 qualifying race, when his anxiously tried to charge to the front and shake out all the cobwebs and frustration from his injury-plagued season a year ago. The move backfired, he found himself mired in traffic and after a deep breath to regroup, used a different game-plan to get to the front. It was a valuable lesson in patience, one he'll need Sunday when he tries to become the first driver at Daytona International Speedway to sweep Speedweeks.
