Power Rankings: Texas Motor Speedway edition

The NASCAR series has put an exciting, controversial afternoon in Martinsville in the rear-view mirror and now sets its sights on an evening race at Texas Motor Speedway for the Samsung Mobile 500 -- after a weekend off to celebrate Easter.

Who's on top of David McGee's Power Rankings? Dale Earnhardt Jr., who is second in points after finishing third Sunday, jumped four spots to No. 1. He's always been tough at TMS, and don't expect anything to change.

The rest of the top five: Greg Biffle, defending series champion Tony Stewart, Matt Kenseth and Kevin Harvick.
