MLB Power Rankings: May, 12 2009

WhatIfSports.com utilizes its award-winning baseball simulation engine to present the most comprehensive and unbiased ranking possible of all 30 teams in baseball each Monday during the regular season.

To come up with the rankings, using only their statistical performance to date this season, each team is simulated against every other team 100 times—50 at home and 50 at the opposing ballpark so that all five pitchers in the current rotation start ten times at each location.

(Note: This means that if a pitcher who was in the rotation was recently put on the DL, he will not be included in the simulations. This is true of position players as well, but and injury to one position player will usually have a lesser impact on the week-to-week results.)
