Power Rankings: Rangers, Phils stay; Rox climb

Who has the power this week?

Is it the Rangers or the Phillies?

How good are the Yankees? And what's going on with the Red Sox?

Here's what we know for sure:

On Monday, the Rockies will take on the Giants in Colorado in the battle for supremacy in the National League West, and in the American League West, the Rangers and Angels will square off in Texas for the top spot in the division.

Don't look now, but the Royals and the Indians, who face each other in a four-game set beginning Monday, are likely to add more intrigue to what's already been an interesting start in the AL Central.

Welcome to this week's edition of the 2011 version of the MLB.com Power Rankings, where fans can now rank their top 15 teams and view their picks right alongside the picks from the experts at MLB.com. Together, the picks from the fans and experts form the "MLB.com Energy Power Rankings presented by Reebok ZigTech."

Fans who participate in the rankings have a chance to win two tickets to watch a team of their choice during the 2011 regular season.

For the second consecutive season, MLB.com set up a panel of experts to vote on the top 15 teams each week. Two former Major League players -- Larry Dierker and Jeff Nelson -- are part of the process, as is Carlton Thompson, vice president and executive editor of MLB.com. Former general manager and current MLB.com analyst Jim Duquette, along with MLB.com columnists Mike Bauman, Hal Bodley, Anthony Castrovince, Dave Feldman, Alden Gonzalez, Marty Noble and Jesse Sanchez are also part of the group. Results will be revealed every Monday through the rest of the regular season.

Agree? Disagree? The power is yours.

4Even with last week.Yankees

The Yankees won two of three against the Rangers over the weekend and are building momentum. Alex Rodriguez, batting an AL-leading .385 with four homers and nine RBIs, has been bothered by stiffness in his left side but does not expect to go on the DL.

The Royals can hit and have just enough pitching to win. They are among the Major League leaders in several offensive categories, including runs, batting average and extra-base hits.

11Moved up from last week.Blue Jays

The Blue Jays trail the first-place Yankees by 2 1/2 games in the AL East standings and should get a boost this week with the return of pitchers Brandon Morrow and Frank Francisco.
