This past week, there were changes at the top of the American League and National League East divisions.

I spoke last week about the Washington Nationals nearing the top of the NL East and coming into today they now have a 2.5 game lead over the New York Mets. It wouldn’t be a stretch to expect them to stay in first from here on out.

The same can’t be said for the Tampa Bay Rays who have also found themselves in first place. The difference with them is the fact that the New York Yankees have lost six in a row and 10 of their last 11. At just three games over .500, the Rays sit as the worst division leader in all of baseball.

Teams that are on a roll coming into this week include the San Francisco Giants, Arizona Diamondbacks and Cleveland Indians.

On the other hand, the Cincinnati Reds had a winless week while the Chicago White Sox and San Diego Padres continue to make us question who they really are.

Here’s the power rankings for the week.
