The D-backs are the hottest team in baseball and one of the season's biggest surprises.
The National League West leaders won their seventh consecutive game Monday and have won 15 of their past 17 contests.
What does the baseball world think of Arizona?
Have the D-backs replaced the Giants as the team to beat in the West, or is it still too early to tell?
What has happened to the Rockies? And is anybody surprised the Phillies have the best record in the game?
It's time to hear your voice.
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 Power Rankings."
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.

This Week's Power Rankings
The return of injured center fielder Shane Victorino to the lineup this week will provide an offensive boost to a club that already boasts the best record in baseball.
The American League Central leaders are looking to rebound from their first rough patch of the season. Over the past six games, the Indians have been outscored, 44-12, with a .125 (4-for-32) average with runners in scoring position.
Slugger Matt Holliday, who has been slowed by tightness in his left quad, has returned to the starting lineup, and Albert Pujols appears to be returning to familiar form. Pujols went 2-for-4 with a home run and two RBIs against the Giants on Monday.
Mark Teixeira has found his power stroke. The first baseman homered for the fourth time in five games and the seventh time in 11 contests Monday. Eleven of his 16 home runs this season have come with runners on base.
Credit goes to manager Kirk Gibson for changing the culture in the clubhouse, and to an offense that has come to life, but the D-backs' bullpen has been lights out, starting with closer J.J. Putz.
The Marlins have lost three of their past four after sweeping a three-game series last week in San Francisco. Hanley Ramirez said his stiff back is causing the worst pain he has ever experienced, and the club is very concerned. He is considered day to day.
The joy has returned to Red Sox Nation. The club has posted a Major League-best 19-9 record in May, improving from last place in the AL East and an 11-15 record at the start of the month to a tie with the Yankees atop the division.
The Braves could use a big hit. They hit .301 with runners in scoring position during their first 42 games, but they have hit just .177 (17-for-96) in those situations over their past 13 games.
The loss of catcher Buster Posey to injury is a big blow to the offense, but help is on the way. Third baseman Pablo Sandoval will start taking batting practice soon and could return to the lineup in two weeks.
The Rangers averaged 3.3 runs per game while Josh Hamilton and Nelson Cruz were out with injuries. They've doubled that (6.7) in the seven games since they came off the DL.
The Brewers have won eight of their past 10 games and continue to make waves in the NL Central. Staff ace Zack Greinke has found his breaking ball. He has 39 strikeouts to just three walks in 28 innings to go along with a 1.14 WHIP.
The Rays have lost seven of their past 10 games and have played 13 consecutive games against teams with .500 or better records. They have gone 5-8 in those games.
Jose Bautista is the undisputed offensive leader of the club -- he's reached base in 43 of 46 games this season -- but Yunel Escobar and Juan Rivera have also had a strong month. Corey Patterson also has 35 hits in May.
Vernon Wells (right groin) and Howard Kendrick (hamstring) could return to the lineup soon. That's good news for a club fighting for the top spot in the AL West.
It's been quite a month for Jay Bruce. He's batting .346 with 12 homers, 32 RBIs and 23 runs scored in May.
