1. JIMMIE JOHNSON — The five-time champion now has won three races in the last four weekends. Be afraid. Be very afraid. Is a sixth championship in the offing? Last week: 3rd.

5. KEVIN HARVICK — A great result for Harvick, who rallied from a bad pit stop to finish second to Johnson. It was Happy’s first top five since Auto Club Speedway. Last week: 9th.
