The opening weeks of the baseball season result in a lot of flux in the MLB Power Rankings at The Wife Hates Sports, which are calculated into a figure that incorporates hitting statistics, pitching numbers, records and more.  Hence, a significant amount of change will likely exist throughout the month of April, as teams establish themselves with specific strengths and weaknesses.

The Boston Red Sox – after an emotional rollercoaster week due to the tragic events at the Boston Marathon – emerge in the top slot, followed by the Texas Rangers, Colorado Rockies, Atlanta Braves and Cincinnati Reds.

This week’s big winners are the Cincinnati Reds and Milwaukee Brewers, each jumping eleven spots, while the big losers are the Oakland A’s, after falling nine slots and out of the top ten.

The entire list of MLB Power Rankings is as follows, featuring some specific team or player related statistics, along with the clubs that had positive or negative jumps in the latest poll:

The Wife Hates Sports MLB Power Rankings system has a method to its madness, attempting to be different and not just rank by popularity and record.  It mixes a secret formula of six completely different categories, meshed into a points system.  The categories don’t just include team results regarding record, but how each team has performed recently, as well as incorporating some statistics on both a team’s offense and pitching staff, too.
