This is an interesting way to do power rankings. From Sportsillustrated.com here are their top 7 and some notables:

The Top teams are 1. Texas Rangers 2. St. Louis Cardinals 3. New York Yankees 4. Atlanta Braves 5. Los Angeles Dodgers 6. Washington Nationals 7. Kansas City Royals (other notables) 11. Los Angeles Angels 12. Philadelphia Phillies 14. Detroit Tigers 15. Tampa Bay Rays 17. Arizona Diamondbacks 23. Boston Red Sox

Here is what they have to say on the Royals:

Kansas City Royals Ranked 7th (last week ranked 11th) WAR Winning Percentage: .544; Current Winning Percentage: .200; WAR Wins: 8; Current Wins: 3 Here's a case where a team's WAR winning percentage can be more telling than its current record. Judging by wins and losses alone, the Royals have been atrocious. But their offensive line of .254/.316/.408 is pretty close to league average and their pitching hasn't been disastrous. The problem has been when the hits have come: Kansas City has hit just .198 in high-leverage situations. The Royals don't have to play much better in order to start winning games -- they just need to start coming through in the clutch.

Here is there explanation on how they do their rankings:

Welcome to the SI.com Power Rankings, powered by FanGraphs. You will probably notice that these Power Rankings don't look like most other Power Rankings you'll see around the web, as our system is based not on the current standings or a gut feeling about team quality, but on how well they've performed at the underlying traits that predict future performance better than wins and losses.

Those traits -- getting on base, hitting for power, running the bases effectively, getting strikeouts while avoiding walks and home runs from their pitchers, turning hits into outs on defense -- are summed up in our Wins Above Replacement metric, and then we've translated each team's total WAR into an expected winning percentage based on the number of games they've played this season. By utilizing WAR, we can better identify which teams are actually playing well and will likely sustain their success going forward.

It's early, but the Texas Rangers are serving notice that the road to the World Series still goes through Arlington. The two-time defending AL champs are running over every team in their path, even thumping a quality Detroit squad over the weekend. They have the best record in baseball, and according to our calculations, they've earned it. While the Angels and Tigers made the big offseason splashes, early returns suggest that Texas is the best team in baseball.
