Stats

Fantasy Bullpen uses many advanced statistical methods in evaluating major league baseball players. In this glossary we will detail the statistics we use.

Hitting

The current sabermetric view on hitting is that a batter has some control over whether a batted ball in a hit or not. Some batter hit the ball farther, harder, and run faster. There are a few basic statistics that I look at when evaluating hitters, and a few more I am working on.

OBP – Quite simple the % of PA that results in the batter getting on base. One of the most important, and simplest, stats in baseball.

SLG - Slugging percentage measures how many bases you gain per AB. Another important and simple stat, however with the key flaw that it values every base equally.

OPS – I like OPS because its easy to calculate, simple, and a great measure of a batters skill level. That doesn’t mean its perfect at all and there are better options like….

wOBA – Weighted on base average is also pretty simple, however difficult to calculate. It is the amount of runs you contribute per plate appearance (scaled to look like OBP). This is a powerful stat, however It does give credit to batters for stuff like reaching base on an error or getting hit by a pitch, something I don’t quite agree with. Probably the best offensive stat out there.

CT% - This is another really simple stat. Sense a theme here? CT% is the % of Abs in which you make contact. This really helps when calculating various expected batting average formulas. The more you make contact the more likely you are to get hits.

GB, FB, LD %s – These are used more for pitchers because you really cant use hits there, but I think this is probably the next step in the sabermetric revolution. Measure what kind of a hit a hit is, how fast, what direction, etc. and you can really break everything down.
