Kevin Harvick, driver of the #29 Budweiser Chevy, won the Tums Fast Pain Relief 500 at Martinsville becoming the first multi-race winner this season. Harvick won last week at the California Speedway with a late race charge and did the same at Martinsville, tracking down Dale Earnhardt Jr. in the closing laps to score the win.   Jr. finished second, just nipping Kyle Busch at the finish line.    The series moves on to Texas for a night race on Saturday.
