Bernie Brewer is not the only one smiling in Milwaukee this week.

There appears to have been a power shift in the National League, and the Brewers are making a charge toward the top of the list.

Have the Brewers topped the Phillies as the most powerful team in the NL, or is it too early to tell? Or are the Braves -- not the Phillies or the Brewers -- the team to beat in the NL?

That's where you come in. It's time to let your vote and your voice be heard.

Welcome to this week's edition of the MLB.com Power Rankings brought to you by Sprint, 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 Power Rankings.

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.

This Week's Power Rankings
This WeekMovementPower PlayerLast Week
1Even with last week.Phillies

Cliff Lee has been dominant on the mound all month. The veteran left-hander is 3-0 in three starts and has allowed two earned runs in 24 innings in August. Third baseman Placido Polanco will provide a much-needed lift to the offense as he comes off the disabled list, especially now that Jimmy Rollins is on the DL.

2Moved up from last week.Yankees

A-Rod is back, the Yankees are in first place and, aside from a minor rift between A.J. Burnett and manager Joe Girardi, all is well in the Bronx. Curtis Granderson's career year could land him the American League MVP Award.

3Moved down from last week.Red Sox

David Ortiz (right heel bursitis) and Jacoby Ellsbury (back contusion) could rejoin the lineup this week. Their return couldn't come at a better time. The Red Sox kick off this week against the Rangers and next week against the Yankees.

4Even with last week.Brewers

Don't look now, but Milwaukee just might be the hottest team in baseball. The club has won 22 of its past 25 games, and 31 of its past 41, and has the widest lead of any of baseball's six division leaders.

4
5Even with last week.Braves

Atlanta is on a roll. The Braves are coming off a three-game sweep of the NL West-leading D-backs and lead the NL Wild Card race by eight games. Chipper Jones is playing like he's 29, not 39.

5
6Even with last week.Rangers

Texas won seven of 10 games on its last road trip, and the bullpen continues to be a strength. Offensively, first baseman Mitch Moreland and veteran Mike Napoli have been picking up the slack in Adrian Beltre's absence.

6
7Moved up from last week.Rays

Don't count the Rays out yet. Tampa Bay has won five in a row and 10 of its past 12 games. It's an uphill climb in the AL East, but anything's possible, right?

8
8Moved up from last week.Angels

The Angels have won four straight and continue to make up ground in the AL West standings. They are 21-8 in their past 29 home games heading into a two-game set against the White Sox that starts Tuesday.

10
9Moved up from last week.Tigers

The Tigers are taking control of the AL Central and coming off a three-game sweep of the second-place Indians. And it gets better for Detroit fans: Justin Verlander pitches Monday.

12
10Moved down from last week.D-backs

Can the slumping D-backs hang on to their narrow lead in the NL West? Arizona has lost five in a row and is batting .162 with nine runs over the past six games. How will the D-backs bounce back?

7
11Moved down from last week.Giants

The 12-game homestand that starts Tuesday is the longest of the season for the second-place Giants. It might also be the most important of the year. Their next nine games will all come at home against teams with losing records.

9
12Moved down from last week.Cardinals

The Cardinals need to make up ground against the Brewers in the NL Central standings but have been playing short-handed lately with Rafael Furcal (thumb) and Ryan Theriot (hamstring) out of the lineup. The good news? Albert Pujols is hitting .421 with four home runs in his past 10 games.

11
13Even with last week.Blue Jays

The Jays have won six of their past 10 games and Jose Bautista's spectacular season continues. He leads the Major Leagues with 36 home runs and is hitting .400 with three home runs and four RBIs in his past 10 games.

13
14Moved up from last week.White Sox

It's been a disappointing season on the South Side, but the White Sox still believe they have a shot at the postseason. The club is back at .500 and trails the first-place Tigers by five games in the AL Central.

15
15Moved down from last week.Indians

The Indians were swept by the first-place Tigers over the weekend and now trail Detroit by a season-high 4 1/2 games in the division. But there's still plenty of baseball left. The Indians are on the verge of a stretch of 39 games over the final 37 days.
