How We Calculate: Our MLB Power Rankings are calculated by aggregating computer rankings from around the web and determining each team’s average ranking. Up or down movement within our rankings versus the previous week is provided for each team. Some of these sites also project teams’ future success. We collect this info and calculate each team’s average win/loss projection, playoff odds and World Series odds.

Our heat chart below shows how each of the five sites we pull from ranks all 30 teams. We pull from FiveThirtyEight (538), numberFire (nF), Massey Ratings (MY), Sagarin (Sag) and Team Rankings (TR).

Standard deviation is a statistical tool used to measure the variance within a set of numbers. In the table below, we use standard deviation to determine which teams are ranked the most and least consistently. A low number indicates that a team is ranked consistently across the five sites we pull from. A high number indicates an inconsistently ranked team.
