The 2012 MLB season is roughly a quarter of the way over, and while there have been a handful of teams that have established themselves as elite at this point, the middle of the pack is made up of nearly half of the MLB.

It has been a season of parity thus far, as 11 teams enter play on Monday in the 19- to 21-win range, and several divisions show the top and bottom teams separated by just a handful of games.

In lieu of a team outlook this week, I have named my top hitter and pitcher for each team at the quarter-pole mark of the season.

Here is a look at this week's MLB power rankings. Check back here each Monday morning for an updated look at where your favorite team stands.
