WAR - Wins Above Replacement, as its name suggests, provides an exact number of wins a particular player is worth above what your average AAA player, or replacement player would provide in his absence. Although this is a very difficult stat to explain (I don't totally get it personally) the stat is beautifully simple in that it provides a precise value of either a pitcher or hitter to his particular team, which enables teams to monetize their worth and properly assign a dollar value.


ERA+ - similar to OPS+ its a more highly sophisticated way of evaluating a pitcher's performance adjusted for park effects, this also is on a numerical basis with 100 as league average.

FIP - short for fielding independent pitching, FIP measures the only aspects of the game that a pitcher has total control over, strikeouts, walks, and home runs. Scaled to ERA, FIP gives a truer indication of a pitcher's true talent by removing the luck apparent with balls in play.


WHIP - Walks and Hits per innings pitched, a little more well known stat, but a good indicator of how effective a pitcher is. Chances are if a guy is walking a lot of guys and giving up a hot of hits, he's not pitching all that well.

xFIP- a variation of FIP which normalizes home run rates as a way to discount aberrational home run rates that are either too high or too low to reasonably sustain.

UZR- Short of Ultimate Zone Rating, this is the number of runs above or below average a fielder is in both range runs and error runs combined. This is a difficult stat to understand because it's not one of those stats you can figure out at home, because it includes a bevy of factors including park effects and speed. As a consequence, its not a perfect stat, but its the best defensive stat we have. Also seen as UZR/150 is the Ultimate Zone rating per 150 games.

RngR - Range Runs is defined as the number of runs above or below average a fielder is, determined by how the fielder is able to get to balls hit in his vicinity. Also not a perfect fielding stat, but one of the many fielding stats that help as as fans get a fuller picture of a player's defensive prowess.
