We are about 51 games through the 2011 season and the serious contenders are beginning to make their mark. My beloved Red Sox make a big jump, and a new team enters the top ten for the first time this season. Let’s see how the top ten fall this week in our Power Rankings.

Let the Debate Begin.

#1 Philadelphia Phillies

The Phillies feasted on the Cincinnati Reds and the unfortunately poor Mets this week, regaining the top spot in our rankings. This team continues to click on all cylinders as they rack up win after win. We all expected great things out the Philly rotation, and I think we are beginning to see exactly just how scary they can be. They now lead the league in quality starts (37) and are second in both ERA (3.02) and WHIP (1.20).

#2 Cleveland Indians

After finding out they had reached the top of our rankings, the Indians promptly forgot how to win. Losing two of three from both the Red sox and Rays, Cleveland had a tough week. Early season surprise Justin Masterson got rocked on Sunday giving up seven runs in five innings (his shortest outing this year). It will be very telling to see how Cleveland responds to its worst week so far this season.

#3 St. Louis Cardinals

The Cardinals went just 4-2 this past week, winning series against San Diego and Colorado. Pitcher Kyle Lohse is now 7-2 with a 2.13 ERA and a .92 WHIP. This kind of pitching will help ease the loss of Wainwright and will be necessary for St. Louis’ hopes down the road. The offense is outstanding, but that will take them only so far.

#4 Boston Red Sox

The Red Sox now have a one game lead in the AL East and went 5-2 on the week winning an important series with Cleveland in the process. Solid substitute starts from Alfredo Aceves and Tim Wakefield have given their potent offense a chance to relax and produce. The lineup is now starting to act as many predicted which has helped the Red Sox reach their highest point in our rankings this year.

#5 Florida Marlins

Even though the Fish got absolutely fried by the Dodger’s Clayton Kershaw on Sunday (CG 2 hitter), they still are only two games back of the mighty Phillies. They do however face two tough series this week against the equally hot Milwaukee Brewers and Arizona Diamondbacks. Leo Nunez now leads the majors with 18 saves and is impressing many in the process.

#6 Atlanta Braves

The Braves seem to fall under the pitching only category these days as their anemic offense ranks towards the bottom in every statistic. There are a few bright spots on the lineup though as Brian McCann and Martin Prado are having really solid years. Favorable matchups against the Padres and Mets this week should yield the Braves another handful of W’s.

#7 New York Yankees

A 3-3 week, which included two loses to the Mariners, has the Bronx Bombers at their lowest spot in our rankings this year. Curtis Granderson now leads one of the most powerful lineups in baseball in AVG (.282), HR’s (16), RBI (37), and hits (55). New York fans can only help but wonder where this was last season, but the Grandy man is finally winning some respect.

#8 San Francisco Giants

A horrible 1-5 week has a lot of people wondering about how good this team actually is. A four game set with St. Louis will definitely answer a few questions. The already struggling offense has now failed to produce a run five times this season, as they continue to squander excellent pitching.

#9 Tampa Bay Rays

The Rays are only 4-6 in their last ten and now sit third in the AL East. After winning two of three from the Indians this weekend, they are now the only team this year to beat Cleveland in two series. Evan Longoria is now hitting leadoff for the Rays and seems to enjoy the spot. He has hit 4-7 in his first two games there.

#10 Milwaukee Brewers

Welcome to the top ten Milwaukee. Now 8-2 in their last ten games, the Brewers are now only two and a half games back of the Cardinals in the NL Central. The two headed monster of Ryan Braun and Prince Fielder are making this lineup one of the more fearsome in the majors. They now also own the best home record in the majors (21-7)

#21 New York Mets

A 2-4 week leaves much to be desired for Mets fans, especially after they touched the .500 mark late last week. However a four game set with Pittsburgh might be just what the doctor ordered. However a team ERA of 4.21 will make any game hard to win. David Wright is expected to have a solid timetable in the next few days and Mets fans everywhere are counting the minutes until his return.
